The European Space Agency (ESA) just released some new snapshots from its Mars Express orbiter that detail the dynamic terrain of the Red Planet’s Acheron Fossae region. One of the photos shows trough-like features called “grabens,” which run about 500 miles (800 kilometers), or roughly the length of Germany. They were shaped from ancient volcanic activity that twisted the surface of Mars almost four billion years ago. Flowing lava from the nearby Alba Mons volcano (not pictured) is likely responsible for the smooth region in the bottom center of the…

While three-dimensional (3D) models are essential tools for scientific discovery and analysis, their potential extends far beyond the lab. Space can often feel distant…
Read MoreEaster is coming late in 2025, astronomically speaking. Here’s why
Saturday night (April 12) brings us the April full moon, which traditionally is known as the “Pink Full Moon.” The Native Americans who once occupied the northern and eastern United States kept track of the seasons by attaching distinctive names to each full moon that occurred at approximate 29-day intervals during the course of the year The “Pink Moon” name is rather deceptive, however, because it might initially give some the idea that on that particular night the full moon will appear to glow with a pinkish or salmon hue.…

The final satellite in NOAA’s GOES-R weather satellite series has a new place in orbit … and a new name. The GOES-19 weather satellite, which launched into orbit in June 2024, has officially taken the place of its predecessor GOES-16 to watch over the Western Hemisphere from its perch 22,236 miles (35,785 kilometers) above us. To mark the milestone, the satellite has the new name of GOES East to serve as the dominant geostationary satellite in the fleet, NOAA officials said in a statement. “With GOES-19 now in operation, NOAA…

Read MoreNASA spacecraft spots monster black hole bursting with X-rays ‘releasing a hundred times more energy than we have seen elsewhere’
We’ve all woken up in a terrible mood from time to time, but a newly observed monster black hole is really having a bad day. The previously inactive supermassive black hole at the heart of the galaxy SDSS1335+0728, located about 300 million light-years away from us, was seen erupting with the longest and most powerful X-ray blasts ever seen from such a cosmic titan. This active phase marks the start of the supermassive black hole devouring matter around it and erupting with short-lived flaring events called quasiperiodic eruptions (QPEs). The…
Read MoreWe now know the shape of notorious asteroid 2024 YR4 that dominated headlines recently — it’s probably ‘suburban,’ too
The asteroid 2024 YR4 — the one that caused a stir earlier this year due to its potential collision course with Earth — has a surprising tale to tell. A new study reports that this space rock likely hails from the central region of the main asteroid belt between Mars and Jupiter — a cosmic “suburb” scientists don’t typically associate with asteroids that cross paths with our planet. Shortly after its discovery late last year, astronomers calculated that 2024 YR4 had a 1.3% chance (1-in-83) of impacting Earth in December…
Read MoreBlack holes as batteries: Could humanity ever harness the energy of these cosmic titans?
Humans are quite rightly fascinated by black holes, but could we ever harness them as an energy source? New research poses this question in order to explore some of the most wonderous cosmic events. Black holes are bounded by outer barriers called event horizons that prevent us from ever viewing their interiors or their hearts, singularities at which all known laws of physics collapse. This means black holes couldn’t be more mysterious. Black holes are also unlike anything found on Earth or in the solar system in another respect: their…
Read MoreA day on Uranus is actually longer than we thought, Hubble Telescope reveals
Uranus just got a little more time on its hands. A fresh analysis of a decade’s worth of Hubble Space Telescope observations shows Uranus takes 17 hours, 14 minutes and 52 seconds to complete a full rotation — that’s 28 seconds longer than the estimate provided by NASA’s Voyager 2 spacecraft nearly four decades ago. In January 1986, Voyager 2 became the first — and so far the only — spacecraft to explore Uranus, and with its data, astronomers pegged the ice giant’s rotation period at 17 hours, 14 minutes…
Read MoreNorth America is ‘dripping’ down into Earth’s mantle, scientists discover
An ancient slab of Earth’s crust buried deep beneath the Midwest is sucking huge swatches of present-day’s North American crust down into the mantle, researchers say. The slab’s pull has created giant “drips” that hang from the underside of the continent down to about 400 miles (640 kilometers) deep inside the mantle, according to a new study. These drips are located beneath an area spanning from Michigan to Nebraska and Alabama, but their presence appears to be impacting the entire continent. The dripping area looks like a large funnel, with…
