Trippy Image From Deep Space Shows Earth and Moon From 180 Million Miles Away

Gizmodo8 hours ago
The Psyche spacecraft is on a six-year journey to reach a metal-rich asteroid by the same name. Well into its voyage, the probe looked back at its home planet and captured a rare view of Earth, accompanied by its Moon, as a mere speck engulfed by the dark void of space.
NASA's Psyche mission launched on October 13, 2023, and is assigned to explore a distant target in the main asteroid belt that's believed to be the exposed core of a protoplanet. Before it reaches its destination, the imaging team behind the mission is testing the spacecraft's ability to capture objects that shine by light reflected from the Sun. The target objects of these tests are awfully familiar—our very own planet and moon—but they were taken from a rather unfamiliar perspective.
In July, scientists on the imaging team snapped multiple, long-exposure photos of Earth and the Moon. The pair is seen amidst a dark background littered with several stars in the constellation Aries. Earth appears as a bright dot, with the Moon sitting right above it. The image was taken from about 180 million miles (290 kilometers) away and offers a rare look at our planet as seen from deep space.
The photo brings the famous Pale Blue Dot to mind, an image of Earth captured by the Voyager 1 spacecraft in 1990. That image was taken from a distance of 3.7 billion miles (6 billion kilometers), with Earth appearing as a mere speck amid the cosmic backdrop.
Although it wasn't captured from the same distance, Psyche's recent image is a similar reminder of Earth's place and size in the solar system. The spacecraft is equipped with a pair of cameras, designed to collect pictures in wavelengths of light that are both visible and invisible to the human eye, to help determine the composition of the metal-rich asteroid.
Psyche needs to travel a total of around 2.2 billion miles to reach the main asteroid belt and enter asteroid Psyche's orbit in late July 2029. The 173-mile-wide (280-kilometer) asteroid orbits the Sun in the outer part of the main asteroid belt between Mars and Jupiter. Scientists believe the space rock might be an exposed core of a planetesimal, or an early planetary building block, which was stripped of its outer layer during the early formation of the solar system.

Birds Across the World Are Singing All Day for a Disturbing Reason

If the songbirds in your neighborhood are waking you up earlier and chirping well into the evening, blame light pollution. Artificial light touches nearly every corner of Earth's surface, and a new study shows that it's messing with birds' biological clocks. Researchers analyzed a global acoustic dataset of more than 60 million recorded birdsongs representing more than 580 diurnal bird species. The findings, published Thursday, August 21, in the journal Science, show that light pollution has prolonged birdsong by an average of 50 minutes per day in the brightest landscapes, such as cities. Birds in these areas begin singing an average of 18 minutes earlier in the morning and stop 32 minutes later in the evening compared with those in the darkest landscapes, underscoring the effects of artificial light on bird behavior across species, space, and seasons. 'Light pollution is a growing concern for human and wildlife health, with current estimates of 80% of the world and more than 99% of U.S. and European populations living under light polluted skies,' study authors Brent Pease and Neil Gilbert told Gizmodo in an email. Pease is an assistant professor of biodiversity conservation at Southern Illinois University, and Gilbert is an assistant professor of biology at Oklahoma State University. 'While the outcomes of this pollution source on human health are widely studied, how it is affecting wildlife across the world is still a developing topic,' they added. Gilbert and Pease used data gathered by the BirdWeather project—a global citizen-science initiative that records and analyzes bird vocalizations—to investigate the impact of light pollution on diurnal birds. They compiled 61 million vocalizations captured between March 2023 and March 2024, then calculated vocalization onset and evening cessation relative to various sunlight phases. The researchers used VIIRS satellite data to generate month-specific light pollution measures for each BirdWeather station location. The Visible Infrared Imaging Radiometer Suite instrument, currently flying on the Suomi NPP and NOAA-20 satellite missions, can observe the brightness of human settlements. This allowed them to analyze the onset and cessation of birdsong alongside light pollution. 'We were surprised by the magnitude of birds' responses,' Pease and Gilbert said. 'On average, under the brightest night skies, a bird's day is extended by nearly an hour. While we expected some behavioral adjustment to the lights at night, we didn't anticipate that it would be this impactful,' they explained. This prolonged activity may affect birds' ability to survive and reproduce in several key ways, according to Gilbert and Pease. For example, 50 minutes of additional activity a day may lead to reduced resting time, potentially resulting in higher caloric needs. On the other hand, extended activity may translate to increased foraging time or increased reproductive output. Parsing this complexity will require further research, but it's clear that our ever-brightening world is changing the way diurnal birds live—and they're not the only ones. 'Light pollution appears to be having pronounced effects on human and wildlife health,' Pease and Gilbert said. 'If the extended day is resulting in sleep debt, as it often does for humans, then we might expect adverse health or population outcomes, further exacerbating the long-term decline of bird populations across the globe.'

‘Alien: Earth' Is Finally Doing What the Movies Have Not

At their core, most of the Alien movies are about corporate greed. The lengths a company, mainly Weyland-Yutani, will go to harness and exploit a power from the deepest reaches of space. Whether that means sacrificing a whole ship of employees, a platoon of soldiers, families, criminals, or cloning dead people, almost every story in the Alien saga is about the idea that getting an alien back to Earth would be a huge benefit to the bottom line of the company. This, of course, never comes to be. In Alien, the xenomorph aboard the Nostromo killed almost everyone on the ship before being blown into space. The story of Alien: Romulus then hinges on the remains of that alien being captured, exploited, and causing another ship to be decimated. Aliens features a plan to sneak a xenomorph back after the trip to LV-426, which fails, and also suggests Weyland-Yutani had yet to succeed in its aim to acquire one decades later. Sending a team to Ripley's prison in Alien 3 also didn't work out, and before the ship in Resurrection crashes on Earth, all manner of xenos are gone. Every single attempt that we've seen to acquire or sneak an alien back to Earth has failed. Or so we thought. In Alien: Earth, which is set a few years before the events of Alien, we now know that not only did at least one fully grown xenomorph make it back to Earth before Ripley and the crew of the Nostromo were woken up, but several viable eggs did too. Unfortunately, Weyland-Yutani had them stolen out from under them by a rival corporation, Prodigy. And now, in the show's most recent episode, we see the beginnings of that ultimate goal: people on Earth studying xenomorphs. It's the one thing Weyland-Yutani always wanted to do but has, and apparently will continue to, fail at. And yet, their loss is now Prodigy's gain. What happens next on Alien: Earth as the study of the xenomorph continues has yet to be revealed. However, we can all but guarantee it won't go smoothly. Before all hell inevitably breaks loose, though, as it always does, many questions remain. Will Prodigy learn anything that makes the risk it's taking worthwhile? Also, is this specific Weyland-Yutani failure the reason why, in a few years, it decides to send the Nostromo off on its doomed side mission? Whatever the case, for fans of the Alien franchise, this really is a dream come true. Years ago, Alien: Resurrection finally showed us scientists studying xenomorphs, but that wasn't on Earth. David the android got to do some of that in Alien: Covenant, too, and off-screen, Alien: Romulus revealed that strides could be made. Now, finally, after years of teasing, we get to see smart, capable people, who don't fear for their lives (yet), with the proper technology and means to figure out what makes these mysterious creatures tick. It's the dream of every greedy slimeballin Alien history, and we get to watch it play out in our homes all summer long. Alien: Earth is currently streaming on FX and Hulu. Want more io9 news?

Astronomers found a tiny moon orbiting Uranus. There are likely more waiting to be spotted

Astronomers using the powerful eye of the James Webb Space Telescope have spotted a previously unknown moon whirling around Uranus, according to NASA. The discovery boosts the number of moons known to be orbiting the ice giant to 29 — and there are likely more waiting to be found. The moon came to light through a series of 40-minute long-exposure images taken by Webb's Near-Infrared Camera on February 2. 'It's a small moon but a significant discovery, which is something that even NASA's Voyager 2 spacecraft didn't see during its flyby nearly 40 years ago,' said Maryame El Moutamid, a lead scientist in the Southwest Research Institute's Solar System Science and Exploration Division in Boulder, Colorado, in a statement. El Moutamid is the principal investigator of a Webb program dedicated to analyzing the structure and dynamics of the typically hidden rings and inner moons of Uranus. The glow of Uranus' rings and the moon's tiny size, measuring about 6 miles (10 kilometers) in diameter, are likely what obscured it from the view of Voyager 2, the only mission that has performed flybys of Uranus and Neptune, as well as telescopes such as Hubble that have observed the solar system's outer planets. It's possible that the moon and some of the material comprising Uranus' rings have a common origin, which could mean the rings and moon are fragments resulting from the same ancient event, El Moutamid said. The moon, temporarily named S/2025 U1, could reveal how Uranus' rings are shaped, whether by gravity or an ancient event, to provide a window into the enigmatic rings' structure, stability and history, she said. 'The discovery raises questions about how many more small moons remain hidden around Uranus and how they interact with its rings,' El Moutamid said. The discovery of moons around planets in our solar system is not a very common occurrence, but it does happen from time around giant planets like Jupiter, Saturn, Uranus and Neptune. 'These planets have many moons, and some are so tiny and faint that we're still discovering them,' El Moutamid said. The newly found moon is the 14th in a system of small moons orbiting Uranus — all of which orbit closer to the planet than its largest moons: Miranda, Ariel, Umbriel, Titania and Oberon. 'It's located about 35,000 miles (56,000 kilometers) from Uranus' center, orbiting the planet's equatorial plane between the orbits of Ophelia (which is just outside of Uranus' main ring system) and Bianca,' El Moutamid said, referring to two other small moons circling the planet. 'Its nearly circular orbit suggests it may have formed near its current location.' Spotting the moon was no easy task because it is tiny, dark and moves quickly, which made it nearly invisible against the background glow of Uranus' rings, El Moutamid said. The high resolution and sensitivity of Webb's Near-Infrared Camera was perfectly suited to find a faint, distant object, she said. Webb's ability to capture infrared light, invisible to the human eye, has also provided glimpses of Uranus' rings and moons, atmosphere and weather during earlier observations. 'Its detection highlights both the dynamic complexity of Uranus's system and the sharp eyes of modern astronomy.' So far, all of Uranus' moons have been named for characters from the works of William Shakespeare and Alexander Pope. The previously unknown moon doesn't have a literary name yet, and the International Astronomical Union, which assigns official names to celestial objects, will need to approve one. Part of the difficulty in determining just how many moons orbit Uranus is the proximity of these natural satellites to the planet and the bright glare of the planet itself, said Scott Sheppard, astronomer at the Carnegie Institution for Science in Washington, DC. Sheppard was not involved in the new observations but helped discover a Uranus moon in 2024. 'This new Uranus moon is a very exciting find since it is so close to Uranus and likely associated with the inner ring system,' Sheppard said. 'This discovery shows the power of the James Webb Space Telescope to be able to image deeper than we ever have before.' No other planet has as many small inner moons as Uranus, said coprincipal investigator Matthew Tiscareno, a senior research scientist of solar system dynamics and planetary rings at the SETI Institute in Mountain View, California. Astronomers don't quite know how the diminutive moons have avoided crashing together because they're so close to one another, but the satellites may act as shepherds for Uranus' narrow rings, according to NASA. 'Their complex inter-relationships with the rings hint at a chaotic history that blurs the boundary between a ring system and a system of moons,' Tiscareno said in a statement. 'Moreover, the new moon is smaller and much fainter than the smallest of the previously known inner moons, making it likely that even more complexity remains to be discovered.' Before Voyager 2's groundbreaking views of Uranus in 1986, only five moons — its largest — had been spotted orbiting the planet, with the first two discovered in 1787 and the fifth in 1948. Voyager 2 found 10 moons during its flyby, ranging from 16 to 96 miles (26 to 154 kilometers) in diameter. Hubble and ground-based telescopes have spotted an additional 13 tiny moons, which range from 8 to 10 miles (12 to 16 kilometers) across and appear darker than asphalt, according to NASA. While the inner moons appear to be made of ice and rock, the moons beyond Oberon are likely asteroids captured in orbit around Uranus, according to the space agency. 'Looking forward, the discovery of this moon underscores how modern astronomy continues to build upon the legacy of missions like Voyager 2, which flew past Uranus on Jan. 24, 1986, and gave humanity its first close-up look at this mysterious world,' El Moutamid said in her statement. 'Now, nearly four decades later, the James Webb Space Telescope is pushing that frontier even farther.' Future Uranus exploration missions planned for the early 2030s, which include an orbiter and an atmospheric probe, could also help astronomers understand the ice giant like never before. Uranus has largely been defined by data gathered during Voyager 2's flyby, but another, more detailed visit to the ice giant, which rotates on its side, is overdue to shed light on the planet's atmospheric dynamics, complex magnetic field and what led to the creation of its extreme tilt and rings. Detailed observations could also reveal whether any of Uranus' moons are ice-covered ocean worlds. The planetary decadal survey, authored by the National Academies of Sciences, Engineering, and Medicine in 2022, recommended the first dedicated Uranus Orbiter and Probe as the next large NASA mission. Currently, it's unclear where the mission fits into NASA's future plans, especially as the agency grapples with the White House's proposal to slash NASA's science budget by as much as half. Sheppard said there are surely more undiscovered Uranus moons that are only a few kilometers in size, but they would be even fainter than the newly detected moon and even harder to find. 'New moons will likely be found either by taking extremely long images with JWST or a future Uranus spacecraft mission,' Sheppard said. Next, El Moutamid and her team want to uncover more details about the new moon's orbit, search for additional moons and support any planning for the Uranus Orbiter and Probe mission. 'Discovering a new moon around Uranus helps scientists better understand how its strange system formed, sheds light on its rings, and prepares us for future missions like NASA's Uranus Orbiter and Probe,' El Moutamid said.
