Science Through Shadows: How Astronomical Alignments Reveal the Universe

When one celestial object passes in front of another, it can cast a shadow that travels across space – and sometimes across Earth. These moments of alignment, known as eclipses, occultations, and transits, allow scientists to study distant objects in remarkable ways.

NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published […]

NASA’s X-59 Experimental Supersonic Aircraft Makes Second Flight

NASA’s quiet supersonic X-59 aircraft made its second flight on Friday, kicking off a series of dozens of test flights in 2026. Although the flight duration was abbreviated due to a technical issue, the team was able to collect information that will inform future tests. “Despite the early landing, this is a good day for the team.
