When it comes to Mars and our ongoing efforts to understand that planet’s ancient habitability, evidence is so far elusive. But scientists have an idea where the evidence is likely hiding: in sediments.

Queen guitar legend Brian May helps analyze NASA's OSIRIS-REx asteroid samples
Music legend Brian May has spoken about his role in the historic NASA OSIRIS-REx mission, which in September returned a sample of the space rock Bennu to Earth.
SpaceX aims to launch 144 missions next year
SpaceX hopes to launch 100 missions this year and ramp its cadence up to 144 flights in 2024, a company representative said during a Senate hearing on Wednesday (Oct. 18).
NBC's 'Quantum Leap' hops back in time to investigate UFOs in this week's spooky episode
A review of this week's 'Quantum Leap' episode, 'Closure Encounters,' which takes Ben Song back to 1949 New Mexico to investigate UFO sightings.
India wants to land astronauts on the moon in 2040
India plans to land astronauts on the moon by 2040 and build a space station by 2035, officials announced on Tuesday (Oct. 17).
Space history and future leap off the screen at NASA's Kennedy Space Center
Guests at NASA's Kennedy Space Center can now see a space shuttle launch, a SpaceX Starship land on the moon and astronauts walk on the surface of Mars, all before they enter the visitor complex.
NASA Mission Had the Perfect View for the Recent Solar Eclipse
Eclipse-gazers across the United States got a chance last weekend to watch as the Moon aligned with the Sun to create an annular eclipse. They watched from the ground for a short experience of not-quite-darkness. NASA’s Deep Space Climate Observatory (DSCVR) caught the action from Earth orbit for a different view of the event.
Canada to launch new satellites to monitor climate change, gather military data
The Canadian government promises it will get new satellites into space soon to extend its famous Radarsat series for Canada's Earth observation needs, climate change and Arctic military surveillance.
'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.
