Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes formed without stars.
"A strong magnetic field is very important for life on a planet."
Exhaust from lunar landers drifts across the moon and contaminates ultra-cold polar craters that are rich in ancient ice and organic clues, a new study reports.
"Most excitingly, this new idea addresses one of the longstanding habitability problems on Europa and is a good sign for the prospects of extraterrestrial life in its ocean."
"Instead of Webb's 6.5-meter diameter, it's like we are observing this region with a 13-meter space telescope."
Tiny delays in pulsar signals measured by SETI scientists could aid the search for gravitational waves and extraterrestrial life.
MAVEN was built to last in orbit until 2030 — that's not looking likely anymore.
"It's really not a question of robotic exploration or human exploration," Ehlmann said. "It is an 'and' — it's robotic and human exploration and how we do these best together."
New discoveries and fresh looks at familiar worlds show how far exoplanet science has come — and how much remains unknown.
"There is a lot to keep us busy."
NASA's Parker Solar Probe captured solar material looping back to the sun, revealing how it recycles magnetic energy and shapes future solar storms.
Scientists have created the first detailed maps of the sun's atmospheric boundary, where solar material breaks free and streams into space.
"The natural question that comes up is: how many more space telescopes will be affected when all these constellations are launched?"
Astronomers have found the strongest evidence yet of an atmosphere around a rocky exoplanet.
"We did the simplest thing that could be done — we just mapped them and pieced them together."
JUICE and the Hubble Space Telescope turned their gazes towards the interstellar visitor in November.
New simulations suggest TRAPPIST-1e's possible methane atmosphere may be a false signal from its star, raising fresh questions about the planet’s habitability.
NASA imaged Comet C/2025 R2 (SWAN) every four minutes for nearly 40 days, marking the longest any comet has been tracked with such frequency.
A new joint analysis from the NOvA and T2K experiments offers the most precise look yet at neutrino behavior, bringing scientists closer to understanding why the universe is made of matter.
Asteroid Bennu samples contain life-friendly sugars, a strange "space-gum," and ancient stardust
"This is a snapshot of where we are very early in the scientific process."
A new set of computer simulations may finally explain several long-standing mysteries surrounding gigantic radio "relics" that appear when galaxy clusters collide.
"All that remained was the particular flat shape."
