The thermal structure of hot gas giant exoplanet atmospheres is likely to be inverted for the hottest planets, a class of planets known as ultra-hot Jupiters. This is the conclusion from astrophysicists based at the Univ...

(University of Colorado at Boulder) An astronaut standing on Mars couldn't see the planet's ultraviolet "nightglow." But this phenomenon could help scientists to better predict the churn of Mars' surprisingly complex atm...

Revenues for Lithuanian Nanosatellite manufacturer NanoAvionics tripled in the last 12 months as the company signed contracts with startups and industry veterans. SpaceNews

European science progressed at a slower pace on the International Space Station in the past month. As a series of spacewalks to power up the space habitat came to an end and two of its passengers left for home Earth, int...

The percentage of small satellites that successfully complete their missions has improved in recent years even as the number of such satellites has dramatically increased. SpaceNews

Scientists have developed a new prediction of the shape of the bubble surrounding our solar system using a model developed with data from NASA missions....

Col. Russell Teehan said commercially developed technologies will be part of the future capabilities of the U.S. Space Force. SpaceNews

Methane and nitrogen glaciers on Pluto expand and "grow" in response to temperature changes on the dwarf planet, new research suggests.

As small satellites become more powerful, manufacturers say they need better ways to manage excess heat generated by their electronics systems. SpaceNews

NASA's first asteroid sampling spacecraft is making final preparations to grab a sample from asteroid Bennu's surface. Next week, the OSIRIS-REx mission will conduct a second rehearsal of its touchdown sequence, practici...

Orbiters are giving us a chance to study the surface of Mars closely, and some of the features that pop to prominence are dry river channels. There are over 10,000 of them. But a new study suggests that glaciers on ancie...

An international team of solar physicists, including academics from Northumbria University, in Newcastle upon Tyne, has recently measured the global magnetic field of the outer most layer of the Sun's atmosphere, the sol...

Our new study, published in Nature Communications, has uncovered some answers.

The Earth has one less asteroid to worry about thanks to the research of an international team of scientists at the Arecibo Observatory in Puerto Rico.

A SpaceX Falcon 9 rocket is expected to send 57 more Starlink satellites into space early Friday morning (Aug. 7). Here's how to watch it live.

Maxar Technologies no longer expects, at least initially, to win any manufacturing contracts for Telesat's future broadband megaconstellation of 300 satellites. SpaceNews

Video: 00:04:35 Join ESA astronauts Thomas Pesquet and Matthias Maurer at NASA's Johnson Space Center in Houston, Texas, USA. In part four of this video series, the astronauts discuss taking photos on the International S...

The launch of a NASA astronomy smallsat mission next year will be postponed by several months after the pandemic delayed assembly of key elements of the spacecraft. SpaceNews

Astronomers used the moon as a mirror to study Earth during a lunar eclipse, simulating a possible search for signs of extraterrestrial life.

Using some cosmic detective work, a team of researchers has found evidence that tiny pieces of asteroids from the inner solar system may have crossed a gap to the outer solar system, a feat once thought to be unlikely.

Taking advantage of a total lunar eclipse, astronomers using NASA's Hubble Space Telescope have detected Earth's own brand of sunscreen--ozone--in our atmosphere. This method simulates how astronomers and astrobiology re...

Evidence of a neutron star hidden deep inside Supernova 1987A helps astronomers solve a 33-year-old mystery surrounding one of the brightest star explosions ever observed.
