The 25 scariest spaceflight moments show dangers in orbit and beyond

There are quite a few times in history when crews ran into trouble, and got out again. That's why good training for the extreme environment of space is a must.

White House says US would respond if Russia targets commercial satellites

The White House has responded to Russia's assertion that commercial satellites are legitimate targets by stating that a U.S. response would follow any such attacks.

Haunting portrait: Webb reveals dust and structure in Pillars of Creation

This is not an ethereal landscape of time-forgotten tombs. Nor are these soot-tinged fingers reaching out. These pillars, flush with gas and dust, ‘bury’ stars that are slowly forming over many millennia. The NASA/ESA/CSA James Webb Space Telescope has snapped this eerie, extremely dusty view of the Pillars of Creation in mid-infrared light – showing us a new view of a familiar landscape.

Astronomy: The oldest scientific discipline

From charting constellations to analyzing exoplanet atmospheres and imaging edges of black holes, astronomy has always strived to understand the nature of the universe and our place in it.

Hubble Space Telescope watches galaxies' destructive dance in new photo

These galaxies may look like they are performing a cosmic waltz, but the spirals are actually trapped in a dance of death that will someday end in a violent crash.

Everything we know about Dune: Part 2

Here’s everything we know about Dune: Part 2 including the release date, plot, cast and more.

New Earth-monitoring weather satellite prepares for launch

The JPSS-2 satellite will seek to better understand the "butterfly effect" of how atmospheric conditions in one part of the world can cause a hurricane in another part.

Chinese launch next week will set stage for another big space-junk crash

The Long March 5B rocket expected to launch China's Mengtian module on Oct. 31 will likely fall back to Earth uncontrolled a week or so later.

SpaceX hasn't flown a Falcon Heavy rocket since 2019. Here's why.

In the 40 months since a Falcon Heavy last took flight, SpaceX has launched more than 100 missions with its workhorse Falcon 9 rocket. So why has the Heavy stayed grounded?

Earth from Space: Svalbard

Extremely high temperatures recorded this summer caused record melting across Svalbard – one of the fastest warming places on the planet. The Copernicus Sentinel-2 mission captured this rare, cloud-free acquisition of the Norwegian archipelago in August 2022.

Scientists choose first Mars samples worthy of return to Earth

The first samples to be taken from Mars and sent to Earth will be sourced from Jezero Crater, where the Perseverance rover has been exploring the crater floor and nearby ancient delta.  The location of an initial cache of samples, called Three Forks, is flat and free of obstacles – an ideal spot for a Mars Sample Return landing and pickup operations.

SpaceX adds 53 more Starlink satellites to internet constellation

SpaceX’s Falcon 9 rocket fires its upper stage engine to propel 53 Starlink internet satellites into orbit. The rocket’s first stage booster and two halves of the payload fairing are visible returning to Earth for recovery and reuse. Credit: Gene Blevins / LA Daily News

SpaceX fired a Falcon 9 rocket off a launching stand in California at sunset Thursday, producing a twilight sky show visible as far away as Texas as the mission delivered 53 more Starlink internet satellites into orbit.

NASA is Mapping Giant Clouds of Methane Released by “Super-Emitters” Across the World

Everybody’s heard of methane. It’s a major part of the atmosphere in places like Uranus and Neptune. On Earth, it’s also part of our atmosphere, where it works to warm things up. Some of it gets there from natural causes. But, a lot of it comes from industrial super-emitters and other human-caused processes. That’s not good because too much methane works, along with other greenhouse gases (like carbon dioxide, or CO2) to “over warm” our atmosphere.

Here are Four Ways JWST Could Detect Alien Life

Less than a year after it went to space, the James Webb Space Telescope (JWST) has already demonstrated its worth many times over. The images it has acquired of distant galaxies, nebulae, exoplanet atmospheres, and deep fields are the most detailed and sensitive ever taken. And yet, one of the most exciting aspects of its mission is just getting started: the search for evidence of life beyond Earth. This will consist of Webb using its powerful infrared instruments to look for chemical signatures associated with life and biological processes (aka. biosignatures).
