NASA releases stunning space photos to mark Hubble anniversary
On April 24, 1990, all 24,000 pounds of the Hubble Space Telescope were tucked away inside the Discovery space shuttle when it launched into space. Thirty-five years later, NASA says Hubble has proven to have "opened a new window to the universe," with more than 1.6 million observations to date filled with compelling and surprising images of galaxies, planets and our own solar system.
To celebrate the anniversary milestone, NASA has released stunning photos taken by the telescope in its decades among the stars.
Among them is an image of Mars, taken 61 million miles from Earth.
"Thin water-ice clouds, revealed by Hubble's unique ultraviolet capability, give the Red Planet a frosty appearance," Hubble said along with the photo on social media.
In a news release commemorating Hubble's decades around the sun, NASA said the telescope "is a glowing success story of America's technological prowess, unyielding scientific curiosity, and a reiteration of our nation's pioneering spirit."
"Its stunning imagery inspired people across the globe, and the data behind those images revealed surprises about everything from early galaxies to planets in our own solar system," said Shawn Domagal-Goldman, acting director of the Astrophysics Division at NASA Headquarters in Washington. "The fact that it is still operating today is a testament to the value of our flagship observatories, and provides critical lessons for the Habitable Worlds Observatory, which we plan to be serviceable in the spirit of Hubble."
Another image captured by Hubble shows the nebula NGC 2899, which NASA's Hubble account on X described as being "sculpted by the outflow of radiation and stellar winds from a 40,000-degree-Fahrenheit dying star at its center."
Hubble has looked at roughly 55,000 astronomical targets during its time in space, resulting in over 22,000 scientific papers as of February. Aside from the James Webb Space Telescope, it has contributed to the biggest dataset for a NASA astrophysics mission, with over 400 terabytes of data. Among the observations it has captured are planetary seasons, black hole jets traveling at nearly the speed of light, stellar convulsions, asteroid collisions and expanding supernova bubbles.
One of those observations, a portion of the star-forming Rosette Nebula, shows dark clouds of hydrogen gas laced with dust.
Hubble's ability to capture the cosmos isn't just visually stunning, but has provided numerous scientific breakthroughs. Before the telescope's launch, telescopes grounded on Earth couldn't see as far into space, limiting estimates for the age of the universe and knowledge of space in general. Hubble was able to capture deep field images that showed galaxies dating back to the early universe, allowing scientists to precisely measure the universe's expansion.
Using the telescope, scientists were also able to determine that supermassive black holes are common among galaxies and measure the atmospheres of exoplanets — and it even contributed to the discovery of dark energy.

Trump's palace coup leaves NASA in limbo
When President-elect Donald Trump nominated Jared Isaacman to become NASA administrator, it seemed like a brilliant choice. Business entrepreneur, private astronaut, Isaacman was just the man to revamp NASA and make it into a catalyst for taking humanity to the moon, Mars and beyond. Isaacman sailed through the confirmation process in the Senate Commerce Committee, chaired by Sen. Ted Cruz (R-Texas), by a vote of 19 to 9. He was poised to be confirmed by the full Senate when something so bizarre happened that it beggars the imagination. The White House suddenly and with no clear reason why, pulled Isaacman's nomination. After months of a confirmation process, NASA was back to square one for getting a new leader. Ars Technica's Eric Berger offered an explanation as to why. 'One mark against Isaacman is that he had recently donated money to Democrats,' he wrote. 'He also indicated opposition to some of the White House's proposed cuts to NASA's science budget.' But these facts were well known even before Trump nominated Isaacman. Trump himself, before he ran for president as a Republican, donated to Democrats and was close friends with Bill and Hillary Clinton. Berger goes on to say that a source told the publication that, 'with Musk's exit, his opponents within the administration sought to punish him by killing Isaacman's nomination.' The idea that Isaacman's nomination is being deep-sixed because of Musk runs contrary to the public praise that the president has given the billionaire rocket and electric car entrepreneur. Trump was uncharacteristically terse in his own social media post. 'After a thorough review of prior associations, I am hereby withdrawing the nomination of Jared Isaacman to head NASA,' he wrote. 'I will soon announce a new nominee who will be mission aligned, and put America First in Space. Thank you for your attention to this matter!' CNN reports that Isaacman's ouster was the result of a palace coup, noting that a source said, 'Musk's exit left room for a faction of people in Trump's inner circle, particularly Sergio Gor, the longtime Trump supporter and director of the White House Presidential Personnel Office, to advocate for installing a different nominee.' The motive seems to be discontent about the outsized influence that Musk has had on the White House and a desire to take him down a peg or two. Isaacman was profoundly gracious, stating in part, 'I am incredibly grateful to President Trump @POTUS, the Senate and all those who supported me throughout this journey. The past six months have been enlightening and, honestly, a bit thrilling. I have gained a much deeper appreciation for the complexities of government and the weight our political leaders carry.' The idea that a man like Isaacman, well respected by the aerospace community, who was predicted to sail through a confirmation vote in the full Senate, could be taken down by an obscure bureaucrat in White House intrigue, motivated by petty spite, is mind boggling. Even Sen. Mark Kelly (D-Ariz.), who has not been fond of Trump's space policy, was appalled. He posted on his X account that Isaacman 'ran into the kind of politics that is damaging our country.' 'Republicans and Democrats supported him as the right guy at the right time for the top job at NASA, but it wasn't enough.' NASA is in for months more of turmoil and uncertainty as the nomination process gets reset and starts grinding its way through the Senate. The draconian, truncated budget proposal is certainly not helpful, either. Congress, which had been supportive of Trump's space policy, is not likely to be pleased by the president's high-handed shivving of his own nominee. Whoever Trump chooses to replace Isaacman as NASA administrator nominee, no matter how qualified, should face some very direct questioning. Trump's NASA budget proposal should be dead on arrival, which, considering the cuts in science and technology, is not necessarily a bad thing. China must be looking at the spectacle of NASA being mired in political wrangling, a leadership vacuum and budget uncertainty with glee. Beijing has its own space ambitions, with a planned crewed lunar landing by 2030. It's possible that the Chinese will steal a march on NASA, with all the damage that will do to America's standing in the world. It didn't have to be this way. Isaacman could be settling in as NASA administrator, deploying his business acumen and vision to lead the space agency to its greatest achievements. Instead, America's space effort has received a self-inflicted blow from which it will be long in recovering, Mark R. Whittington, who writes frequently about space policy, has published a political study of space exploration entitled 'Why is It So Hard to Go Back to the Moon?' as well as 'The Moon, Mars and Beyond,' and, most recently, 'Why is America Going Back to the Moon?' He blogs at Curmudgeons Corner.

NASA Pulls the Plug on Europa Lander, but Scientists Propose a Plan B
NASA engineers have spent the past decade developing a rugged, partially autonomous lander designed to explore Europa, one of Jupiter's most intriguing moons. The space agency got cold feet over the project, but engineers are now targeting a new destination for the probe: Enceladus. Europa has long been a prime target in the search for extraterrestrial biology because scientists suspect it harbors a subsurface ocean beneath its icy crust, potentially teeming with microbial life. But the robot—packed with radiation shielding, cutting-edge software, and ice-drilling appendages—won't be going anywhere anytime soon. In a recent paper in Science Robotics, engineers at NASA's Jet Propulsion Laboratory (JPL) outlined the design and testing of what was once the Europa Lander prototype, a four-legged robotic explorer built to survive the brutal surface conditions of the Jovian moon. The robot was designed to walk—as opposed to roll—analyze terrain, collect samples, and drill into Europa's icy crust—all with minimal guidance from Earth, due to the major communication lag between our planet and the moon 568 million miles (914 million kilometers) away. Designed to operate autonomously for hours at a time, the bot came equipped with stereoscopic cameras, a robotic arm, LED lights, and a suite of specialized materials tough enough to endure harsh radiation and bone-chilling cold. Temperatures on the moon range from about -210 degrees Fahrenheit (-134 degrees Celsius) at its equator to as low as -370 degrees F (-223 degrees C) at its poles. After years of development—including testing in JPL's labs, advanced simulations, and a final field trial on icy terrain in Alaska—the Europa Lander aced its tests. It was ready to take on the solar system's frosty frontier. But the space agency has now pulled the plug on the mission. According to the team, the challenges of getting to Europa—its radiation exposure, immense distance, and short observation windows—proved too daunting for NASA's higher-ups. And that's before you take into consideration the devastating budget cuts planned by the Trump administration, which would see the agency's funding fall from $7.3 billion to $3.9 billion. The lander, once the centerpiece of a bold astrobiology initiative, is now essentially mothballed. But the engineers aren't giving up. They're now lobbying for the robot to get a second shot—on Enceladus, Saturn's ice-covered moon, which also boasts a subsurface ocean and has proven more favorable for robotic exploration. Enceladus is still frigid, but has lower radiation and better access windows than Europa. Whether the ice-walker gets a new lease on its semi-autonomous life remains to be seen. But the robot was built for a moonwalk—albeit a relatively rigid and clanky one—and it deserves its moment.

Northern Lights Seen Glowing Over Earth in Breathtaking Video Shared by NASA Astronaut: Watch
A NASA astronaut shared a stunning video of the northern lights from space Col. Anne McClain took the footage from the International Space Station The lights, also known as the aurora borealis, were caused by a small geomagnetic stormA NASA astronaut shared a rare and stunning video of the northern lights from space. The footage was shared by Col. Anne McClain, who is onboard the SpaceX Dragon spacecraft docked at the International Space Station (ISS). She specifically shared her view of the lights — also called the aurora borealis — from the Cupola, which is the dome-shaped panoramic control tower on the station. 'Auroras from space always draw crewmembers to the Cupola. I love how this one illuminated our Dragon, and I also love the dance of satellites on the left in the latter part of the video,' she captioned the video on X. 'It's interesting how the aurora creeps along the top of the atmosphere as it comes up over the horizon,' she added. 'I have added traveling to see auroras from Earth to my bucket list!' In an X post also shared on June 2, NASA astronaut Nichole 'Vapor' Ayers, who is also on the ISS, explained that the 'sun has been pretty active over the last week, which means some phenomenal auroras!' A forecast from the National Oceanic and Atmospheric Administration (NOAA) stated that geomagnetic storms created an increased chance of seeing the Northern Lights this past week, per the BBC. According to NOAA, a geomagnetic storm is a disturbance of Earth's magnetosphere — a.k.a. the region around the planet dominated by a magnetic field. The disturbances occur when there is an exchange of energy between solar wind and the 'space environment' surrounding Earth. NOAA states that while these storms can create beautiful auroras, large storms can disrupt navigation systems and even cause harmful currents to Earth's power grids — though the most recent storms have been too mild to do so. And as to why the northern lights emit different colors?
