Mercury Retrograde Starts Today — Here's The Truth Behind The Fear
Today, Mercury enters retrograde. From July 17 to Aug. 10, Mercury will appear to move backward in the night sky. According to astrologers — who will be out in force — Mercury retrograde in 2025 will cause chaos. The ancient belief that the positioning of the stars and planets affects the way events occur on Earth has Mercury's retrograde causing problems with communication, transport and technology.
It's all absolute nonsense — and for reasons you might not expect — yet actually understanding Mercury in retrograde does reveal something exquisite about the solar system.
Here's everything you need to know about Mercury's retrograde motion in 2025.
What Is Mercury Retrograde?
Mercury retrograde occurs when Earth overtakes Mercury in its orbit, causing Mercury to appear to move backward in Earth's sky. Mercury is the smallest planet in our solar system and the one that is closest to the sun. It takes Mercury 88 days to orbit the sun once, while Earth takes 365 days. That's just over four Mercury orbits in an Earth year. Thus, three or four times each Earth year, Mercury appears to travel backward across the sky — because Earth overtakes Mercury. Astronomers call the period where it appears to go backward apparent retrograde motion — or Mercury retrograde.
Mercury And Mythology
The ancient Greeks associated Mercury with the swift messenger of the gods, Hermes (the Roman Mercury). According to the European Southern Observatory, Hermes/Mercury was the god of translators and interpreters, served as a messenger for all the other gods, and ruled over wealth, good fortune, commerce, fertility, and thievery.
There you have it — the laundry list of what astrologers pretend that Mercury in retrograde affects in your life.

Can You Blame Mercury Retrograde?
Astrology is popular right now, but that doesn't affect the truth about Mercury retrograde — it's an optical illusion. Anything that happens to you in the next month or so connected to anything said to be related to Mercury's apparent (not actual) movements is, of course, complete nonsense. Associating real-life consequences with a planet's erratic movements would be strange — that mechanism doesn't exist — but to Mercury, retrograde is not real.
Retrograde motion has no physical influence on Earth — it's like blaming something on a rainbow. Worse, almost nobody who ever worries about Mercury retrograde has ever seen the planet with their own eyes — I've even been mistakenly told by a professional astronomer that Mercury is impossible to see with the naked eye (I've seen it well over a dozen times).
Mercury And The 'Planetary Alignment'
Shortly after Mercury has exited retrograde, it will become visible in the pre-dawn sky as it moves away from the sun's glare. Even better, it will form part of a pretty 'planet parade.' Although often called a planetary alignment, the planets will appear in the same region of the sky but will not be precisely aligned in a straight line.
Best seen one hour before sunrise in the eastern sky, from Sunday to Wednesday, August 17-20, Saturn, Jupiter, Venus and Mercury will form a graceful arc in the pre-dawn sky across four consecutive mornings, with a waning crescent moon moving past them, getting slimmer each morning. The highlight will be on Aug. 20, when a 9% crescent moon appears very close to Venus.

Everything Is As Is Should Be
So if apparent retrograde motion sounds ominous — or maybe just confusing — rest assured that Mercury retrograde is neither rare nor dangerous. Despite the myths and mistakes that endure around the phenomenon, it's nothing more than an optical illusion resulting from planetary motion.
There is no chaos. Everything is as it should be. Mercury retrograde is merely an optical illusion created by our changing perspective on Earth as we orbit the sun.
Wishing you clear skies and wide eyes.

In The AI Age, Star Trek's Still Alive
The Starship Enterprise flies over an orange planet in 'The Man Trap,' the premiere episode of 'Star ... More Trek,' which aired on September 8, 1966. (Photo by CBS) It's the age of AI, a time of runaway innovation – more and more of our lives are impacted by digital systems running on electronic hardware, and a lot of what used to be science fiction is now science fact. And then there's Star Trek – the enduring legacy of those who dreamed of space exploration and advanced technology back in the very analog days of the mid-to-late twentieth century. It wasn't too long ago that the ENIAC at UPENN and Project Whirlwind at MIT were humming away, mammoth systems with tape and spinning wheels. And as those large mainframes started to give way to the personal computer, as a new generation of digital users came of age, Star Trek was telling its stories: of a futuristic spaceship festooned with high-tech buttons, lights and dials that supported amazing capabilities. Some of those, with LLM capability, are now reality as well. The Star Trek Set Tour in Historic NY The Star Trek Set Tour experience in Ticonderoga, NY is just down the way from historic Fort Ticonderoga, where a little more than 250 years ago the French and British fought the seven years' war, before the formal foundation of the nascent United States of America. Only a couple of hundred or so years later, look at what we have built. Nearby, in a former Ticonderoga supermarket, James Cawley has recreated a lot of the set pieces and costumes of the original Star Trek show - that takes place 250 years in a fictional future. And it's amazing. The place is open to the public, for a reasonable admission fee, and many have walked through its halls. William Shatner has visited a dozen times, too. I recently took my annual trip there and got to talk to Cawley about his project. Speaking to him, you get a sort of picture of what it was like to be involved on the ground floor, recreating all of these timepieces in a new world where the designs are so retro. In the late 1980s Cawley cold called the studio during the Star Trek Next Generation production and landed a job on the costume staff. When his boss there passed away he left him the original set blue prints to the 1960s TV series which he use to recreate the set. He said he also rewatched the original three seasons of shows to be able to get the look and feel of the sets. 'It hit at the right moment in time, where it needed to say what it said, and reach the people that it reached,' he said, of the original Star Trek show. 'Kennedy had been killed, and we were going through a lot as a nation, and Star Trek had the courage to go on TV and say: 'Nope it's going to be OK. We're going to get there, and we're going to do it together.' He talked about how media changed from VHS and DVD to Blu-ray and 4K, and how, in that intervening age, computing hardware changed, too. 'We've had to take things apart and redo them,' he said, showing off some of the set work that visitors see as they move through the space. The project, he said, has evoked a strong reaction in more than a few people. Some cry. Some don't want to leave. All of this, to me, speaks to the power of nostalgia – as our lives change so much, we like to interact with the past. The Serene Setting As for why this museum of sorts is located here, in Ticonderoga, and not in a big city, Cawley did point out the practicality of the choice. 'You're looking at 13,000 square feet,' he said. '(It would take) millions and millions of dollars to do this in a big city, and then it's not practical. You wouldn't sell enough tickets to warrant that - they couldn't keep the Star Trek experience in Las Vegas going for a length of time, because real estate is expensive, and things change, so I think here, it works, because it's a small community.' Star Trek Through the Lens of AI Think about this: in the 1970s and 1980s, we experienced a premonition of AI through the iconography of shows like Star Trek. As you look at that dated gear, and the types of stagework that cast and crew did, you can see the foreshadowing of everything we now enjoy due to the work of neural nets. My Visit: A Visual Experience As I toured, I got to see some of the visuals that the original actors would have seen as they went 'where no man had gone before.' Here are some of the photos I took while experiencing the set. Captain's chair on the bridge of the enterpriseShip's corridor Another shot of the bridge Sick bay The location At the helm Transporter room - me beaming back to the shop And I think this really showcases how many of us feel as we contemplate a future with AI: We're seeing it through the lens of vintage sci-fi. Just a thought.

Why MAGA hates science so much
Against all the evidence of horrific, devastating weather around us, climate change is still a 'hoax.' A measles outbreak sparked by anti-vaccine conspiracy theorists now extends beyond Texas to 34 states. Republicans are doing all they can to shut down funding for medical research. Why does MAGA hate science? Shall we count the ways? Because scientific advances don't discriminate between the 'worthy' and those considered unworthy, and because some in the billionaire class think they deserve to live much longer than you do. As they prep their fancy-shmancy bunkers or delude themselves that they can one day head off to Mars to escape their wanton destruction of the Earth, the billionaire bros know they can avail themselves and their children of lifesaving vaccinations and other health care services that they are putting out of reach for many of us. But it's not just the small — and small-minded, and small-hearted — wealthy libertarian or right-wing elite. Working people who choose to wear MAGA red caps hate science for their own reasons: It tells them things about disease and environmental destruction and, say, women's reproductive health that they cannot bear to face. Scientific findings often do not jibe with their religious beliefs. If you believe the Earth is 6,000 years old and were never taught how to distinguish between faith and knowledge, you're naturally going to have a testy relationship with science. By its nature of openness to new ideas, scientific inquiry exemplifies the secular worldview of liberals. Science levels the playing field. It's woke. Scientists discriminate about the significance of evidence, but they do not discriminate about the significance of different human beings. (That is what the MAGA faithful think their religion is for — because Republicans have spent a long time perverting Christianity, too, to justify their greed and bigotry.) From reading the writers of the Enlightenment, Thomas Jefferson knew science was evening out the social playing field. In an article for Smithsonian magazine, historian Stephen E. Ambrose notes that amid all the contradictions of his personal life, Jefferson never relinquished his idealism about all men being created equal: In his last message to America, on June 24, 1826, ten days before he died on July 4 (the same day that John Adams died), Jefferson declined an invitation to be in Washington for the 50th anniversary of the Declaration of Independence. He wrote, 'All eyes are opened, or opening to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them.' There's the danger to those who consider themselves superior — by race, color, creed or position on the Forbes annual list of billionaires — to the mass of men and women. Scientific advancements make us ever more aware that we are all the same and should enjoy the same basic rights to education, health care, civil liberties like voting, freedom of and freedom from religion, and the freedom to read or otherwise consume whatever opinions or cultural works we choose — the very things that the current occupant of the White House and his MAGA followers are working to take away from us. Beyond the historical friction between science and religious beliefs (for which earlier scientists could be imprisoned or burned at the stake), the main reason MAGA hates science is human-caused global climate change. Al Gore famously called global warming an 'inconvenient truth,' but Donald Trump persists in calling it 'a hoax,' while defunding climate research, green technology, NOAA and FEMA. The COVID pandemic gave MAGA followers many more incoherent reasons to distrust science, while watching 'their favorite president' politicize every aspect of the response. Apparently, millions would rather suffer mightily — or even die, as many willfully unvaccinated people did — than admit they were wrong. It's a sad aspect of human nature to feel we have such sunk costs in our often-wrongheaded opinions that we are willing to perish for them. I was a biology major in college for a few years, with vague plans of medical school, vaguely until I switched to journalism. I would not pretend to be a scientist based on that curtailed education, but I did spend 36 years in medical publishing. As a production editor and later as a submission systems manager, I came to understand the significant work of researchers and the selfless work of the many peer reviewers who help editors determine which studies merit publication. For many journals I worked with, the acceptance rates were astonishingly small. MAGA conspiracy heads might call that publication process elitist, and claim that people with worthwhile ideas are being kept out of the conversation. Most people in the sciences, however, understand the process as separating the wheat from the chaff by culling out the many papers that for one reason or another — perhaps poor design or insignificant findings — fail to advance scientific knowledge. But you don't need any understanding of science to understand that what Trump and his party of grifters and religious zealots are doing to universities by withholding research funding will be economically devastating to this country, slowing scientific progress and seriously disrupting the lives and careers of many researchers, technicians, lab assistants and students. The long-term negative effects of Trump's attack on science, which are also part of the full-spectrum MAGA assault on education and the nonpartisan civil service, will likely be even worse. Students will be increasingly reluctant to pursue careers in science. Only a months ago, STEM courses in high school and college were viewed as critical to the future of American ingenuity and enterprise, a big part of what actually made America great. It's impossible to gauge just how much damage will be done as we ban vaccines, deny climate science and make measles great again. Many MAGA supporters don't want to share 'their' America with brown people who may or may not be citizens; too many of them welcome the persecution and deportation of longtime U.S. residents who put in long hours at child care centers, hotels and restaurants, construction and landscaping companies, hospitals and nursing homes, and in agricultural fields, doing the thankless and often grueling work of picking and delivering the crops that feed the nation. Britain's decision to leave the European Union — one of the worst self-inflicted wounds of recent political history — has cost the U.K. an estimated 6% drop in GDP so far. The probable result of MAGA's lust to spend billions on hiring more masked, secret police-style ICE agents to deport hard-working, tax-paying immigrants, even if we look beyond the human suffering, will be a Brexit-level recession on steroids. Ultimately, what our felonious, ever-grifting president wants to do is to destroy all expertise in this country. That's what autocrats do. The manchild MAGA leader can't stand for any so-called experts to question him when he makes idiotic suggestions about public health proposes setting off nuclear bombs inside a hurricane or tries to change the longstanding name of a geographical feature to gratify his fragile ego. He wants to claim that his supposedly big and beautiful bill is the most popular legislation in history and that he's the greatest president ever, and doesn't want to hear egghead historians tell him otherwise. Trump hates to be questioned — so he hates journalists, scientists and anyone else with the kind of education that encourages critical thinking. That's why he has surrounded himself with an entire Cabinet of white nationalist frat boys, shameless sycophants and fellow grifters — not to mention a supermajority of right-wing Supreme Court justices who appear ready to hand him absolute power. 'American Robin,' a poem by Barbara Crooker that was recently featured in George Bilgere's 'Poetry Town' newsletter, is about our inability to respond appropriately to the devastation of human-made climate change. But it applies equally well to all the anti-science, misogynist, racist, Dark Enlightenment nonsense coming from the right that seeks to rob you, your children and your grandchildren of a financially and environmentally secure future. It begins this way: Here's that bird again, launching from the rhododendron, banging his forehead on my living room window. Thump. Thump. Does he see his own reflection in the glass or does he see a rival, a threat to his nest? I hang a black raptor silhouette in the middle square, but that does not deter him. Knock yourself out, I keep thinking. Next, I try cardboard, then a sheet of newspaper smeared with its terrible news. He comes back. Do I admire him for his persistence or shrug at his stupidity? Thunk. Thunk. Read the whole poem; I'll wait. One could read Crooker's dismay at the American robin's thumps and thunks against her windowpane as a rhyme for the name of a certain infamous conman turned populist demagogue. But that is perhaps unfair — to the poet and the bird. This article previously appeared in slightly different form at Medium. Used by permission.

New STEM camp helps create engineering minded workforce
MORGANTOWN — Claire Drainer was already dominating at rockets as captain of her East Fairmont High rocketry team, so she tried balloons next. Drainer was one of 17 girls at a new week long summer camp called SpaceTrek, held at the West Virginia University Statler College of Engineering. 'It's amazing, it's a really good opportunity,' Drainer said. 'You get to meet a lot of really nice people and you get to do a lot of things you wouldn't normally get to do.' SpaceTrek originated at Kentucky's Morehead State University, primarily designed to bring more women into Science, Technology, Engineering and Mathematics. It's made for young women entering grades 9-12 or their first year of college. Professor David Martinelli imported the program from Morehead to WVU, intending to adapt it for Appalachian needs. This is its first year here. The program itself teaches basic space systems engineering. The girls learn the fundamentals of electronics, wave motion and the electromagnetic spectrum, among other disciplines, as they put together a cricket satellite for launch aboard a balloon. The balloons climb as high as six kilometers into the atmosphere. After the launch, the team acts as a ground station, by pointing an antenna into the sky and picking up the radio signals the satellite puts out. The girls then use those signals to chart how the radio frequency the satellite is transmitting on changes as it ascends. State Sen. Mike Oliverio, R-Monongalia County, had to rally after graft funding for the program didn't come through in time. Typically, the program recruits during the fall semester for summer session. Oliverio, along with his wife Melissa, wrote to 54 West Virginia school superintendents and reached out to faculty, principals and STEM clubs. Word reached Drainer's grandmother, who told her granddaughter about it. On Thursday, Drainer's grandmother and her grandfather, Ed Buckner, were on hand to show support. 'I think this is a good opportunity for these kids to be introduced to STEM and be involved in STEM,' Buckner said. 'It's a good opportunity because girls would not be exposed to this kind of environment, with the training they get in the classroom. For instance, soldering and electricy, things like that. There's not an opportunity for them in everyday life to be exposed to that.' Melissa Oliverio knows first hand the value of programs aimed at young women. In her youth, she attended debate camp at Wake Forest, which sowed the seeds for her to enter law school later. Now as an adult, and despite the fact she wasn't a STEM student, she wanted to make a similar experience available to other young women in rural counties. 'I believe in the value of women learning with other women,' she said. 'This is just a tremendous opportunity, and we just had to try to help get the word out.' Martinelli said the majority of the girls came from McDowell and Mingo counties. Martinelli said those are some areas that have a disconnect with WVU and the school would love to increase the awareness of higher education there. Having the parents there on the first day of the camp was valuable, and after touring the engineering complex, the parents walked away understanding the value of sending their kids to college. Three of the girls came from East Fairmont High. Wes Deadrick, director of NASA's Katherine Johnson IV&V facility in the I-79 High Tech Park in Fairmont, was also present watching the balloon launches. 'You can spend a lot of time in the classroom and lab, but this is really where the rubber hits the road out here,' he said. Although the NASA facility does more work with software coding and ensuring no mission-ending errors are propagating before a mission launch, and not balloons or atmosphere science, he said programs like SpaceTrek create an important STEM pipeline that gets students excited with the hands-on applications. 'It gives us an engineering-minded workforce, having students that are homegrown that we can pull from the area,' Deadrick said. 'We'd love to hire West Virginians. They're dedicated, hard-working, have some grit and they tend to stay with us.' Solve the daily Crossword
