Two NASA astronauts will conduct a spacewalk today (March 18) that was delayed by the first-ever medical evacuation of the ISS, and you can watch the action live.
Conventional SETI (Search For Extraterrestrial Intelligence) strategies have long been built on the idea that intelligent extraterrestrials (ETI) would aim to communicate with other intelligent civilizations along a very narrow band of the electromagnetic spectrum, preferably in the radio spectrum.
The Large Hadron Collider’s subatomic discoveries didn’t stop with the Higgs boson: This week, scientists at Europe’s CERN research center announced that the collider’s LHCb experiment has detected a doubly charmed particle that’s like a proton, but four times as weighty.
The research could shed light on how black holes vomit out matter and how this influences their home galaxies.
Paul Atreides' kids, a Duncan Idaho comeback (kinda), and Robert Pattinson's creepy new role.
Samples returned from Ryugu contain all five nucleobases, just like from asteroid Bennu. The find suggests life’s ingredients could have come from outside Earth.
Space exploration represents one of humanity's greatest achievements, pushing the boundaries of science, engineering, and human endurance. This document outlines some of the most significant milestones in the history of space exploration.
A civilization capable of interstellar travel may also be one that has moved beyond conquest, excess and ecological self-destruction — and it therefore may not want to talk to us.
A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, guanine, cytosine, thymine, and uracil.
ExpressVPN is rated as the easiest VPN to use and one of the most secure VPN services around, now with a $300 discount and four months free, it also adds incredible value to its repertoire.
SpaceX launched two Falcon 9 rockets on March 17, each carrying Starlink satellites into low Earth orbit. The company now has more than 10,000 active satellites in its constellation.
No major meteor showers are active at this time.
The dust storm created travel complications and other issues for Texans.
NASA has pushed the rollout of its next moon rocket to March 20, but is still targeting April 1 for the launch of its first crewed mission to the moon in more than half a century.
"At last we will have revenge."
Oxygen has been the most important gas in our search for life among the cosmos thus far. On Earth, we have it in abundance because it is produced by biological synthesis. But that might not be the case on other planets, so even if we do find a very clear high oxygen signal in the atmosphere of an exoplanet, it might not be a clear indication that life exists there. A new paper, available in pre-print on arXiv, from Margaret Turcotte Seavey and a team of researchers from institutions like the NASA Goddard Space Flight Center and Johns Hopkins University, adds some additional context to what else might be going on in those atmospheres. In particular, they note that if there’s even a little bit of water vapor, it can make a big difference in whether a lifeless rock looks like a living, thriving world.
Aurora chasers, keep your eyes on the skies later this week as an incoming coronal mass ejection could spark favorable conditions for widespread northern lights displays.
From phone boxes and flux capacitors to black holes and hot tubs, sci-fi has created plenty of ways to explore the fourth dimension.
A successful deep-space manoeuvre has put ESA’s Hera spacecraft on course for its rendezvous with the Didymos binary asteroid system later this year.
Blue Origin and NASA's Jet Propulsion Laboratory are teaming up to design an asteroid-defense spacecraft that will deploy a variety of deflection technologies.
