James Webb Telescope detects rotten-egg gas on alien worlds for the first time
Astronomers have detected a smelly gas best known for the odor of rotten eggs—hydrogen sulfide—in the atmospheres of four giant planets far beyond our...
How a rare element could fuel the next generation of space missions
Scientists at the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) are taking a fresh look at neptunium, a rare radioactive metal that...
Scientists finally solve the mystery of how the most common planets form
Astronomers have finally figured out how the most common types of planets in our galaxy are formed—by watching a set of baby planets grow...
Astronomers spot one of the earliest galaxy clusters ever discovered
Astronomers using two of NASA’s most powerful space telescopes have discovered a massive cluster of galaxies forming much earlier in the universe than scientists...
Did two moons crash to create Titan? New study uncovers dramatic origin story
Saturn’s giant moon Titan and the planet’s famous rings may share a dramatic origin story.
A new study suggests that Titan could have formed when...
Astronomers find new way to detect supermassive black hole pairs
Scientists believe that when galaxies collide and merge, the supermassive black holes at their centers should eventually pair up and orbit each other.
These enormous...
Living in space can change where your brain sits in your skull
Going to space is harsh on the human body, and as a new study from our research team finds, the brain shifts upward and...
Mars’ “young” volcanoes tell a story of long, hidden activity
Volcanoes may look like simple mountains that erupted once and then fell silent, but in reality they are often the surface expression of complex...
Astronomers watch a giant star quietly collapse into a black hole
Astronomers have captured one of the clearest views ever of a massive star dying—not in a dramatic supernova explosion, but by quietly collapsing into...
Astronomers discover “inside-out” planet system that defies cosmic rules
Astronomers have discovered a surprising planetary system that does not follow the usual rules of how planets form.
The finding, led by researchers from the...
How big can a planet get? Scientists have new answers
When it comes to planets, bigger is not always easier to understand. The largest planets in the universe are gas giants—massive worlds made mostly...

There are mysteries at Venus. It’s time for an astrobiology mission
When scientists detected phosphine in Venus’ atmosphere in 2020, it triggered renewed, animated discussions about Venus and its potential habitability.
It would be weird if...
Astronauts could take an asteroid ferry from Earth to Mars
This idea really is quite a fascinating one.
Currently a trip to Mars would require large amounts of air, water and other resources to sustain...
Saturn’s mini moon harbors a hidden ocean
In an astonishing discovery, astronomers have uncovered compelling evidence of a vast ocean lurking beneath the icy shell of Saturn's diminutive moon, Mimas, often...
