More than four months after it was certified to fly national security payloads for the United States government, United Launch Alliance is on the cusp of launching just such a mission with its Vulcan rocket.
'Alien: Earth' is the first-ever Alien TV show and it's finally arrived. Here's how to watch 'Alien: Earth' wherever you are on the planet.
Earth orbit is becoming increasingly crowded. With over 11 000 active satellites and many thousands more expected in the coming years as well as over 1.2 million pieces of space debris greater than 1 cm, the risk of in-orbit collisions has turned into a daily operational concern. ESA is investing in automation technologies that can help satellite operators respond more effectively to collision risks.
On October 14th, 2024, NASA's Europa Clipper mission began its long journey to Jupiter's icy moon Europa. On March 1st, the probe reached Mars, where it conducted a gravity-assist maneuver. While orbiting the Red Planet, mission controllers back on Earth took the opportunity to test the probe's Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON). Once it reaches Europa, Clipper will use this radar instrument to probe beneath the moon's icy sheet and search for pockets of water that could lie within.
Our powerful, modern, ground-based telescopes have to deal with a lot of noise in the starlight they observe. The noise comes from Earth's atmosphere, which forces telescopes to use solutions like adaptive optics to filter it out. Researchers at the University of Warwick in the UK, in partnership with Spanish institutions, are developing a method to use that noise to measure greenhouse gases (GHGs) in Earth's atmosphere.
Scotland-based Skyrora has received the first U.K.-issued vertical launch license for a homegrown company, enabling rocket launches from SaxaVord Spaceport in the Shetland Islands.
Our quiz will test your smarts of which planets go where in our solar system.
"This particular meteor that entered the atmosphere has a long history before it made it to the ground of McDonough".
Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in the first billion years after the Big Bang, moving one step closer to understanding how early galaxies grow.
Fast radio bursts (FRBs) last around a millisecond and in doing so encode otherwise unattainable information on the plasma which permeates our Universe, providing insights into magnetic fields and gas distributions. In a paper authored by Manisha Caleb from the University of Sydney, the team report upon the discovery of FRB 20240304B which lies at a redshift of 2.148 +/- 0.001 corresponding to just 3 billion years after the Big Bang.
It seems simple at first. The Moon and Mars are less massive than Earth and have weaker gravity. To test how a rover will traverse their surfaces, engineers make less massive engineering versions of rovers and test them in simulated surface conditions here on Earth. Since the Moon's gravity is six times weaker than Earth's, for example, engineers make versions of lunar rovers that are one sixth as massive. The data then tells engineers what they need to know.
Cassiopeia is a distinctive constellation in the northern sky, easily recognized by its prominent 'W' or 'M' shape, depending on its orientation in the night sky. It is named after the boastful Queen Cassiopeia in Greek mythology.
Before the Xenomorph crash-lands on streaming, we talked to five Alien: Earth cast members about the difficulties and fun of navigating the giant sci-fi show.
Scientists are making milestones on NASA's Roman Space Telescope as Trump continues to threaten the agency's science budget.
ESA's Mars Express spacecraft has been imaging the dynamic Acheron Fossae region of Mars for more than 20 years.
A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering fresh clues about how galaxies grew in the early universe.
The Perseid meteor shower takes place each year as Earth travels through the debris shed by comet 109P/Swift-Tuttle.
Lucy is already well on its way to Jupiter’s Trojan asteroids. But that doesn't mean that it can’t make some improvements to its trajectory along the way. A new paper suggests it might be possible to nudge Lucy into a slightly different orbit, allowing it to pass an as-yet-undiscovered asteroid sometime during its exploration of the L5 cloud of Trojan around Jupiter. If completed, it could lend an entirely new research target to Lucy’s repertoire and further define the differences between the two Trojan clouds.
A team of astronomers have achieved a milestone in stellar physics by using the James Webb Space Telescope (JWST) to peer beneath the surface activity of TRAPPIST-1, one of the most famous exoplanet host stars. Their study has revealed the hidden magnetic features on this volatile red dwarf, opening new possibilities for understanding both stellar behaviour and the habitability of nearby worlds.
This long-exposure image from the International Space Station shows the growing tension between celestial beauty and human expansion into space.
Chaotic turbulence in primordial clouds of gas may have prevented the formation of extremely massive stars, according to new simulations by Taiwanese astronomers. The early universe consisted primarily of hydrogen […]
