'Astronaut archaeology' could improve space station design. Here's how

New mysteries aboard the International Space Station came to light during a space archaeology project tracking crew use of key spaces. Cake frosting, pegboards and dry wipes all came under scrutiny for better space habitat design.

This Dark Nebula Hides an Enormous Star

The birth of a star is a spectacular event that plays out behind a veil of gas and dust. It’s a detailed process that takes millions of years to play out. Once a star leaves its protostar stage behind and begins its life of fusion, the star’s powerful radiative output blows the veil away.

Air Showers Ruin Astrophotos, but They Could be a New Method for Studying the Universe

Cosmic rays are a fascinating and potentially hazardous phenomenon. These high-energy particles typically consist of protons that have been stripped of their electrons and accelerated to nearly the speed of light. When these rays collide with Earth’s atmosphere, an enormous amount of secondary particles known as an “air shower” results. Ordinarily, these showers are a source of frustration for astronomers since they leave “tracks” on telescope images that obscure the celestial objects (asteroids, stars, galaxies, exoplanets, etc.) being observed.

How AI-powered lasers could help with space debris

A network of space-based lasers could help nudge debris away from collision courses with the International Space Station, according to new research.

Jupiter's volcanic moon Io looks stunning in new Juno probe photos

NASA's Juno spacecraft photographed Jupiter's moon Io during an Oct. 15 flyby, showing its tortured, volcanically-active surface.

New 'galactic atlas' offers stunning details of 400,000 galaxies near the Milky Way

The new Siena Galaxy Atlas is an information gold mine for astronomers and a free gallery of galaxy portraits for the public.

The Combination of Oxygen and Methane Could Reveal the Presence of Life on Another World

In searching for life in the Universe, a field known as astrobiology, scientists rely on Earth as a template for biological and evolutionary processes. This includes searching for Earth analogs, rocky planets that orbit within their parent star’s habitable zone (HZ) and have atmospheres composed of nitrogen, oxygen, and carbon dioxide. However, Earth’s atmosphere has evolved considerably over time from a toxic plume of nitrogen, carbon dioxide, and traces of volcanic gas. Over time, the emergence of photosynthetic organisms caused a transition, leading to the atmosphere we see today.

Hubble Telescope captures the bright core of a loosely wound spiral galaxy (photo)

An intermediate spiral galaxy, called IC 5332, was photographed face-on by the Hubble Space Telescope, capturing the galaxy’s large, circular structure and winding spiral arms glittering with stars.

A massive 'zombie' star is rampaging away from its home cluster

A long-dead white dwarf star is running away from Hyades star cluster — and it could help astronomers solve a number of cosmic mysteries.

Orionid Meteors Fly; Two Moons Shadow Jupiter

Bundle up and enjoy the Orionid meteor shower under moonless skies this week. Don't miss the warm-up act, either, when two of Jupiter's moons pair up in a captivating double-shadow transit.

Welding issues stall Artemis 2 moon rocket's assembly, but 2024 mission still on track: report

Welding issues are holding up a part of the Artemis 2 moon rocket's core stage assembly, a report suggests. But NASA and contractor Boeing continue to build the powerful booster for its 2024 mission.

'For All Mankind' Season 4 explores an asteroid and the lines between science and commerce (video)

'For All Mankind’s' upcoming fourth season just debuted at NYCC 2023, and series fans should expect the mix of alternate history drama and optimistic sci-fi they’ve come to love.

NASA's Parker Solar Probe smashes record for fastest human-made object

NASA's Parker Solar Probe has reached a record-breaking speed as it gets a gravitational assist from Venus to fall closer to the sun's scorching surface.

NASA astronaut snaps photo of solar eclipse from the space station

NASA astronaut Jasmin Moghbeli snapped a photo of the Oct. 14 solar eclipse from the International Space Station, showing the moon taking a bite out of the sun.

Dwarf planet Ceres could be a great place to hunt for alien life. Here's why

Asteroid impacts on dwarf planet Ceres influenced the presence of organic aliphatic molecules, according to new research.

Galactic archeology reveals Milky Way's neighbor Andromeda has a violent past

A new chemical analysis of stars in Andromeda has revealed the galaxy next door had a more chaotic upbringing than the Milky Way, defined by a galactic clash and merger.

An Exoplanet so Hot it has Clouds Made of Quartz

A recent study published in The Astrophysical Journal Letters used data obtained by the James Webb Space Telescope’s (JWST) Mid-Infrared Instrument (MIRI) to identify the presence of quartz nanocrystals in the upper atmosphere of WASP-17 b, an exoplanet whose mass and radius are approximately 0.78 and 1.87 that of Jupiter, respectively, and is located approximately 1,324 light-years from Earth. WASP-17 b is classified as a “puffy” hot Jupiter due to its 3.7-day orbital period, meaning the extreme temperatures could cause unique chemical processes to occur within its atmosphere, but the astronomers were still surprised by the findings.

Spaceflight is Polluting the Atmosphere with Metal

Humans can’t seem to interact with the environment at all without fouling it in some way. From plastic bags in the ocean’s deepest regions to soot on Himalayan glaciers, our waste is finding its way into Earth’s most difficult-to-reach places.
