Plus NOAA's GOES-19 satellite spies the lunar disk crossing the face of our parent star.
The Bahamas has given SpaceX permission to resume rocket landings in the country, which were paused last year after a Starship test flight explosion caused a debris shower.
Just a few hundred light-years from Earth, the famous variable star Mira A is huffing and puffing its outer layers to space. Its most recent mass-loss event ejected more material at higher velocity than in past events. A team of astronomers led by Theo Khouri of Chalmers University in Sweden discovered two large asymmetrical clouds of material expanding away from Mira A.
If a pair of black holes coalesce into one, much of that vast energy can be released in a few seconds.
Traversing the galaxy from places yet known, a few interstellar objects have taken a quick dip into our solar system. Astronomers look to nearby planet-forming stellar systems as possible launching posts.
There’s been plenty in the news about 3I/ATLAS over the course of the past 8 months. Our third confirmed interstellar visitor went behind the Sun during its closest approach, but reemerged in December with plenty of eyes watching it. Papers describing what it looks like following its closest brush with the power of a star in probably billions of years are starting to come out, including a new one available in pre-print on arXiv from Carey Lisse of Johns Hopkins University and his co-authors, which shows how much the comet - and it is definitely a comet - has changed in the matter of only a few months.
Astronomers know that supermassive black holes (SMBH) can inhibit star formation. These behemoths, which seem to be present in the center of large galaxies like ours, inject energy into their surroundings, heating up star-forming gas. Gas needs to be cool to collapse and form stars, so active SMBH put a damper on the process.

The NASA/SpaceX Crew-12 mission launched four astronauts on a journey to the International Space Station.

When we think of ice on Mars, we typically think of the poles, where we can see it visibly through probes and even ground-based telescopes. But the poles are hard to access, and even more so given the restrictions on exploration there due to potential biological contamination. Scientists have long hoped to find water closer to the equator, making it more accessible to human explorers. There are parts of the mid-latitudes of Mars that appear to be glaciers covered by thick layers of dust and rock. So are these features really holding massive reserves of water close to where humans might first step foot on the Red Planet? They might be, according to a new paper from M.A. de Pablo and their co-authors, recently published in Icarus.
An unusual tidal disruption event spotted by astronomers may be the result of an elusive intermediate mass black hole ripping apart a star.
Each year, the world’s leading climate scientists evaluate the most critical evidence on how our planet is changing. Their assessments draw heavily on data from Earth-observing satellites – and the latest report delivers a stark warning: the planet’s energy balance is drifting further out of alignment, ocean warming is now accelerating, and the land’s capacity to absorb carbon is declining, along with other troubling trends.
Elon Musk isn't the first person to propose the use of mass drivers on the moon. He's following in the footsteps of space visionary Gerard O'Neill, who floated the idea back in 1974.
Should you buy a named-brand camera lens or go third-party?
The Milky Way's galactic center should be home to many pulsars, but for some reason, we can't find them. New research identified a candidate pulsar very near the MW's center. If it can be confirmed, it's a chance to test General Relativity.
This past weekend, ground crews at the Kennedy Space Center replaced a filter in the ground support equipment used for propellant loading. This filter was suspected of reducing the flow of liquid hydrogen into the Core Stage during the wet dress rehearsal of the *Artemis II* rocket on Feb. 12th. The test provided the engineers with enough data to prepare for a second wet dress rehearsal, which NASA is targeting for Thursday, Feb. 19th. This test will put the launch team and supporting teams through a full range of operations.
Io is the innermost of the four Galilean moons orbiting Jupiter, distinguished as the most volcanically active world in the Solar System. Its extreme geological activity is a direct result of the immense tidal forces exerted by Jupiter, Europa, and Ganymede.
A massive upheaval in the Saturnian system could have also led to the moon Hyperion.
Every planet in the Solar System is mysterious in its own way. How did Venus evolve into such a hellscape? Did Mars ever support life? How did life on Earth get started?
