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 kilometers) of Earth, or about …

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 aftershocks over a six-week period. Seeing an …

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 world. The study …

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 board a NASA launch rocket. The mission is …

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 explanation closer to home? Now …

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 by the end of the 2030s from any of a number …

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 northwestern Canada on Saturday (Feb. 11) and …

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. Southwest. This heat wave, which started around July 7, tied or broke several all-time …
The SWOT satellite, or the Surface Water and Ocean Topography mission, is now encapsulated in its payload fairing in preparation for launch. Technicians at the SpaceX processing facility at Vandenberg Space Force Base in California completed the operation and will soon mate the fairing to the top of a Falcon 9 rocket. The fairing protects …

The discovery could help scientists learn more about the movements of Earth’s tectonic plates, which not only create mountains and earthquakes, but also contributed to forming environments with the right chemical and physical conditions to support life on early Earth. Our planet’s outermost layer is the crust — which we live on — and below …
