Interstellar space: What is it and where does it begin?
Interstellar space is filled with atoms and molecules, 99% of which is gas, and just 1% is cosmic dust.
NASA’s Psyche Mission is Back on. It’ll Launch Towards its Metal Asteroid Target Later This Year
NASA’s Psyche mission is back on track for launch and is now scheduled for a potential October 2023 launch date, according to an October 2022 statement from NASA. This comes after missing its originally planned launch date between August and October of 2022, and becoming subject to an independent review board, whose results were announced in November 2022.
A Hybrid Fission/Fusion Reactor Could be the Best way to get Through the ice on Europa
In the coming years, NASA and the European Space Agency (ESA) will send two robotic missions to explore Jupiter’s icy moon Europa. These are none other than NASA’s Europa Clipper and the ESA’s Jupiter Icy Moons Explorer (JUICE), which will launch in 2024, and 2023 (respectively). Once they arrive by the 2030s, they will study Europa’s surface with a series of flybys to determine if its interior ocean could support life. These will be the first astrobiology missions to an icy moon in the outer Solar System, collectively known as “Ocean Worlds.”
Rare, 'rule-breaking' quasicrystal found in chunk of 'fossilized' lightning
A type of crystal that breaks the rules of ordinary crystallography has been found in a tube of melted sand from Nebraska.
UV radiation pulse played a role in a mass extinction event, fossilized pollen reveals
250 million-year-old pollen suggests radiation played a role in mass extinction event.
How did Dimorphos Form?
The otherwise unremarkable double asteroid of Didymos and Dimorphos made headlines as the target of NASA’s successful Double Asteroid Redirect Test (DART) mission. With new details about the system emerging, astronomers have put together a hypothesis of how this strange double asteroid came to be.
Guardians of the Galaxy's Groot finally gets an origin story in new Marvel Comics series
Marvel Comics is releasing a new "Groot" solo series this spring that reveals the origin story of the tree-like Guardians of the Galaxy team member.
How to view and photograph comets
As comet C/2022 E3 (ZTF) nears the sun, get the best sights and images of this celestial encounter with our handy guide.
See Venus and Saturn snuggle in the sky Sunday (Jan. 22)
Venus and Saturn will be in conjunction on Sunday (Jan. 22), appearing close enough together in the sky to both be seen through a telescope. The close pairing will also be visible to the naked-eye.
Why Does the Butterfly Nebula Look Like This?
The Butterfly Nebula is changing, and astronomers are puzzled as to why these changes are occurring. Observations of this planetary nebula show dramatic changes in the butterfly’s ‘wings’ in just 11 years.
'Impossible' neutron stars could explain strange flashes
Neutron-star mergers could create hypermassive neutron stars that are the fastest spinning stars in the universe.
Circumpolar Comet ZTF (C/2022 E3) is Here!
Forget the hype and go outside to enjoy the real thing — a relatively bright comet you can see in binoculars from a dark sky.
Galaxies in early universe were surprisingly diverse, James Webb Space Telescope finds
Galaxies in the early universe were much more varied and mature than previously thought, according to observations made by NASA's James Webb Space Telescope.
We finally know why mysterious waves appear to survive the journey through Earth's turbulent 'shock' region
When solar winds bombard Earth's magnetosphere, they create waves that shouldn't be able to traverse a turbulent region called the shock. New research demonstrates how this appears to happen.
Looking back at the eruption that shook the world
One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga, spewing volcanic material up to 58 km into the atmosphere. It brought a nearly 15 m tsunami that crashed ashore, destroying villages, and creating a sonic boom that rippled around the world – twice.

A U.S. military data relay satellite and a rideshare platform with its own suite of payloads rocketed into a sunset sky over Florida’s Space Coast Sunday on a Falcon Heavy launcher, putting on a dazzling show for local residents and visitors as the rocket’s two side boosters returned to Cape Canaveral for landing.
Cosmic Noon was Billions of Years ago, When Many Galaxies Were Filled With Star-Forming Nebulae Like This
You’re looking at NGC 346, a star cluster 210 light years away that is energetically pumping out brand new stars from a dense cloud of gas and dust. Between 10 and 11 billion years ago, nearly all galaxies in the Universe underwent an era of intense star formation similar to what we see in NGC 346. This flurry of stellar birth is poetically nicknamed cosmic noon. Since then, star formation in the Universe has gradually dwindled, though it still blazes away in small pockets. By studying NGC 346 and other clusters like it, we can learn more about the era of cosmic noon and the evolution of galaxies.
Many of the World’s Greatest Observatories Suffer from Some Light Pollution
In a recent study published in the Monthly Notices of the Royal Astronomical Society, an international team of researchers examined the levels of light pollution at astronomical observatories from around the world to better understand how artificial light is impacting night sky observations in hopes of taking steps to reduce it. But how important is it to preserve the scientific productivity of astronomical observatories from the dangers of light pollution, as noted in the study’s opening statement?
SpaceX's Falcon Heavy rocket launches classified mission for US Space Force
SpaceX's Falcon Heavy launched on its fifth-ever mission on Sunday (Jan. 15), sending multiple satellites aloft for the U.S. Space Force.
