Peering through obscuring clouds of dust, the MIRI instrument has revealed networks of giant cavities and blown-out bubbles in the gaseous arms of distant galaxies. Researchers using NASA’s James Webb Space Telescope are getting their first look at star formation, gas, and dust in nearby galaxies...

      A close approach of an asteroid roughly the size and shape of the Empire State Building gave astronomers the perfect opportunity to image the space rock in detail using planetary radar. On Feb. 3, the asteroid, called 2011 AG5, came withing about 1.1 million miles (1.8 million...

The technique is being developed to detect venusquakes. A new study details how, in 2019, it made the first balloon-borne detection of a quake much closer to home. Between July 4 and July 6, 2019, a sequence of powerful earthquakes rumbled near Ridgecrest, California, triggering more than 10,000...

To assess how climate warming will change risks such as crop failures and wildfires, it’s necessary to look at how the risks are likely to interact. Troubles never come singly, the proverb says. A new NASA study shows that the old saying will become increasingly true of climate troubles in a warmer...

NASA will in 2026 launch Israel’s first space telescope into orbit, where it will scan the universe for events such as stars colliding or exploding, the Weizmann Institute of Science said in a statement Tuesday. Ultraviolet Transient Astronomy Satellite, or ULTRASAT, will be carried into space on...

When unidentified flying objects began being spotted over the US and Canada, there was quite a stir among amateur ufologists. UFO discussion forums lit up with theories about the origins and purpose of these floating entities – were they sent by intelligent lifeforms from outer space or was there an...

  Relatively soon, some prominent astrobiologists say, we will most likely have either found compelling evidence for extraterrestrial life or banished its possible existence to the ever shrinking edges of the cosmos beyond the rapidly expanding reach of our observations. Such answers could come...

The three objects blasted out of the sky recently by U.S. fighter jets likely weren’t doing anything nefarious up there, President Joe Biden said. The mystery objects were shot down with Sidewinder air-to-air missiles off the coast of northern Alaska on Friday (Feb. 10), over the Yukon in...

    While one science instrument mapped the dome of high pressure that settled over the southwestern U.S. in early July, another captured ground surface temperatures. Just weeks after the Pacific Northwest endured record-shattering temperatures, another heat wave scorched the U.S...
