Prime Video's brutally brilliant animated superhero series returns today!
Earth was once a magma ocean world, just as all rocky worlds were early in their development, according to theory. As the very young Earth cooled, only the outer core remained molten, wrapped around a solid inner core and covered by the solid mantle and crust. This arrangement, along with coriolis forces, is what sustains our protective magnetosphere.
SpaceX conducted a static fire test with the first stage of its V3 Starship on Monday (March 16), a milestone moment for this bigger, more powerful megarocket variant.
NASA’s Star-Planet Activity Research CubeSat (SPARCS) is a small space telescope that launched to space on January 11th, 2026. Created by NASA and researchers from the School of Earth and Space Exploration (SESE) at the University of Arizona, the mission is tasked with monitoring the flares and sunspot activity of low-mass stars (M-type red dwarfs and K-type orange dwarfs). The telescope is equipped with far- and near-ultraviolet instruments to assess the habitability of the space environment around planets orbiting these stars.

Auroras may be visible from Alaska to Illinois tonight as several coronal mass ejections are forecast to impact within the next couple of days.
Greek mythology has given a name to a great many objects in our solar system. But perhaps one of the least well understood are the Trojans, named after the people of Troy featured in The Iliad. When astronomers refer to them, they are normally talking about a group of over 10,000 confirmed asteroids orbiting at the Lagrange points both in front of and behind Jupiter on its orbit around the Sun. But, more generally, astronomers can now use the term to refer to any co-orbital setup - indeed almost every planet in our solar system has Trojans, though not as many as Jupiter. Which also leads to the belief that “exotrojans” must exist around other stars. Despite our best efforts with initiatives like the TROY project, so far we have yet to find one. But a new paper published in The Astrophysical Journal by Jackson Taylor of West Virginia University and an abundance of co-authors took the hunt to one of the most extreme environments in the universe: pulsar binary systems.
NASA's X-59 jet looks ready to fly into the sunset in this new image taken before its second test flight.
Comet K1, whose full name is Comet C/2025 K1 (ATLAS), had just passed its closest approach to the Sun and was heading out of the Solar System. Though it had been intact just days before, K1 fragmented into at least four pieces while the NASA/ESA Hubble Space Telescope was watching. The odds of that happening while Hubble viewed the comet are extraordinarily miniscule.
Winter constellations shine defiantly in the face of spring as galaxy season and zodiacal light beckon.

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.
