In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star.

Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool stars. In the habitable zone, liquid water can still exist on the orbiting planet’s surface.

The team, which included University of Michigan astronomer and NASA Sagan Fellow Ryan MacDonald, published its study in the journal The Astrophysical Journal Letters.

Scientists removed the outer lid of OSIRIS-REx’s sample canister on Tuesday (Sept. 26). But a full reveal of the mission’s asteroid sample is still two weeks away.

A metallic-looking rock that smashed through the roof of a residential home in New Jersey’s Hopewell Township earlier this week is indeed a meteorite — a rare one about 4.6 billion years old, scientists confirmed on Thursday (May 11).

“It was obvious right away from looking at it that it was a meteorite in a class called stony chondrite,” Nathan Magee, chair of the physics department at The College of New Jersey (TCNJ), whose office was contacted by the Hopewell Township police soon after the rock was found on Monday (May 8), told Space.com.

The James Webb Telescope detected a POSSIBLE sign of LIFE on a far away exoplanet, K2-18b. Here’s the real-talk on what’s happening, and why scientists are h…

NASA astronaut Frank Rubio is finishing up the longest single flight in U.S. space history at 371 days.

Using snapshots taken over 20 years with NASA’s Chandra X-ray Observatory, astronomers have learned important new details about an eruption from Eta Carinae witnessed on Earth in the mid-19th century.

Chandra data spanning decades has been combined into a new movie that contains frames of Eta Carinae from 1999, 2003, 2009, 2014, and 2020. Astronomers used the Chandra observations, along with data from ESA’s (European Space Agency’s) XMM-Newton, to watch as the stellar eruption from 180 years ago continues to expand into space at speeds up to 4.5 million miles per hour. The new insights gleaned from Eta Carinae show how different space observatories can work together to help us understand changes in the universe that unfold on human timescales.

A paper describing these results appears in The Astrophysical Journal.

Thousands of disk galaxies like our own Milky Way were spotted in the early universe, where they shouldn’t exist.

The Mars Ascent Vehicle will become the first rocket to launch from another planet for NASA and ESA’s Mars Sample Return mission.

NASA has released footage captured by its Mars Ascent Vehicle (MAV) team as they performed wind tunnel tests at the space agency’s historic Marshall Space Flight Center.

The US space agency has successfully completed wind tunnel tests on 3D-printed scale models of the MAV, a blog post from NASA reveals.
