Rocket Lab will launch a satellite for a confidential customer early Friday morning (June 20), and you can watch the action live.
For centuries Mars has been called "the Red Planet" and there's a scientific reason why.
A powerful new technique is poised to revolutionize how astronomers observe black holes, by producing sharp, multicolored images that could reveal their dynamic evolution in real time.
The sun will reach its most northern point on June 20, marking the start of the summer season in the Northern Hemisphere.
This 4+ Lego set is colorful and fun, ideal for young Marvel fans looking for an early introduction to building Lego.
Imagine scanning the night sky for signs of alien technology using the same systems that hunt for exploding stars. This is exactly what researchers are now doing, transforming astronomical alert systems originally designed to catch supernovae into powerful tools for detecting potential technosignatures, the evidence of advanced civilisations beyond Earth.
Star formation peaked during the Cosmic Noon, which spanned from 10 to 12 billion years ago. During Cosmic Noon, star formation was 10 to 100 times greater than it is now. New research shows that a particular class of galaxy was experiencing its first intense burst of star formation during this time. Were these galaxies the progenitors of galaxies like the Milky Way?
NASA and the Department of Defense practice recovery procedures for an abort scenario in the upcoming Artemis 2 mission.
Blue Origin's next suborbital flight is scheduled to launch on Saturday (June 21), carrying a private crew of six.
"These small galaxies punch well above their weight."
The monsterous 85-mile-wide comet C/2014 UN271 isn't just the largest icy rock in the Oort Cloud, it's the second most distant that is chemically active.
Auroras may be visible from Alaska to New Hampshire as geomagnetic activity remains unsettled.
The European Space Agency looked back on its heritage and looked forward to a sustainable future on the fourth day of the International Paris Air Show.
Using the XMM-Newton telescope, astronomers have discovered a vast 23 million light-year-wide tendril connecting galactic clusters and containing much of the universe's missing matter.
SpaceX's newest Starship vehicle exploded on a stand in Texas late Wednesday night (June 18), as it was being prepped for the program's 10th-ever test flight.
Astronomers have discovered a huge filament of hot gas bridging four galaxy clusters. At 10 times as massive as our galaxy, the thread could contain some of the Universe’s ‘missing’ matter, addressing a decades-long mystery.

SpaceX’s next Starship vehicle was destroyed in a catastrophic explosion shortly after 11 p.m. CT (0400 UTC) Wednesday as it was being readied for a static fire test at the company’s Massey facility, near Starbase, Texas.
If super massive black holes (SMBH) were given a job description, it would tell them to park themselves in the middle of a massive galaxy and consume as much gas, dust, and even stars as they could. Like teenage boys in front of a well-stocked fridge, they're happy to oblige. However, even voracious SMBHs have limits, and astronomers have watched as one of them reached its limit.
In the 1960s, scientists became acutely aware of a problem with the Universe's "mass budget." Based on the observed rotational curves of galaxies, they determined that about 85% of the Universe's mass was invisible, leading to the theory of Dark Matter. Scientists have also been aware for some time that much of the "normal" or baryonic matter (that which we can see) in the Universe was also unaccounted for. This has prompted multiple efforts to probe the Universe for this "missing" mass, using everything from X-ray emissions and ultraviolet observations of distant quasars to find hints of where it might be hiding.
