Water on the moon? New study narrows down the mostly likely locations

Water likely accumulated on the moon slowly over billions of years, rather than during one big event, according to a new study by an international team of scientists. The researchers, including Paul Hayne, a planetary scientist at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder, have published their findings […]

Artemis astronauts pass behind moon, expected communications cut starts

The four Artemis astronauts on a lunar flyby are now unreachable by NASA scientists on Earth, an expected communications blackout anticipated to last some 40 minutes as their spacecraft passes behind the moon.

If life exists in Venus’s atmosphere, it could have come from Earth

The theory of panspermia holds that life is spread through the cosmos via asteroids, comets, and other objects. When the building blocks of life emerge on one planet, impacts can eject surface material into space, which then carries these seeds to other worlds. For decades, scientists have debated whether this could have occurred between Earth […]

Artemis II crew breaks Apollo 13 record, reaching 252,760 miles from Earth

Astronomers thought the early universe was full of hydrogen: Now they’ve found it

The Eberly Telescope Dark Energy Experiment (HETDEX) has discovered tens of thousands of gigantic hydrogen gas halos, called “Lyman-alpha nebulae,” surrounding galaxies 10 billion to 12 billion years ago. Known as Cosmic Noon, this is an epoch in the early universe when galaxies were growing their fastest. To spur this growth, they would have needed […]

‘Hot Jupiter’ orbiting a metal-poor star discovered

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new “hot Jupiter” exoplanet. The newfound alien world, designated TOI-7169 b, orbits a metal-poor star, which is rare among exoplanets. The finding was detailed in a paper published March 26 on the arXiv pre-print server.

An aerobot with ISRU capabilities could explore Venus’ atmosphere for years

In Dante’s “Divine Comedy,” Hell is described as an “inferno” with nine concentric circles, the entrance of which has a sign that reads “Abandon all hope, ye who enter here.” For the planets of the solar system, Venus is about as close to this description as one can get. On the surface, temperatures are hot […]
