What is quantum gravity? Scientists think it could explain the beginning of our universe

April 30, 2026

Scientists have redefined gravity to explain the Big Bang and perhaps change our picture of the earliest moments of the cosmos. This new framework of “quantum gravity” may explain aspects of the Big Bang that Albert Einstein’s 1915 theory of gravity, general relativity, fails to account for — maybe even doing away with the challenging concept of a singularity existing prior to the dawn of…

Is Tatooine the norm? Planets may prefer living with two suns instead of one

April 30, 2026

Planets may form more easily around pairs of stars than around single stars like the sun, according to new research. Binary star systems, in which two stars orbit each other, are common throughout the Milky Way — and, in fact, even our sun may not have always been alone.

Aurora expert captures rare pulsating northern lights in remarkable detail: 'One of the most profound sightings of my career'

April 29, 2026

When Tom Kerss, chief aurora chaser for the Norwegian coastal voyage operator Hurtigruten, was looking back through footage from his latest season of northern lights voyages, he stumbled upon something truly remarkable. “I’ve been chasing the Northern Lights for more…

Scientists learn how much baby stars in Orion weigh - by watching their dance moves

April 29, 2026

By peering through thick veils of gas and dust, radio astronomers have been able to watch young binary stars orbit around one another in the heart of star-forming clouds – and, in the process, have revealed the stars’ masses. Stars are born in vast clouds of molecular hydrogen gas laced with heavy elements. When one of these clouds fragments into parts, gravity causes pockets within the…

Could the moon ever be blockaded? Experts predict cislunar space could be the next Strait of Hormuz

April 29, 2026

The ongoing military conflict regarding Iran and the Strait of Hormuz may well mirror a future situation off-Earth — the use of cislunar space, the region between the moon and our planet. Think blockades, seizing of ships, impacts on the global economy, repercussions in…

Astrobotic fires next-generation 'rotating detonation rocket engine' in record-breaking test (video)

April 28, 2026

Pittsburgh-based Astrobotic has completed a successful series of hot-fire tests of its rotating detonation rocket engine prototype Chakram, marking a key milestone toward bringing the experimental propulsion technology to flight readiness. Rotating detonation rocket…

AI sped up James Webb Space Telescope data analysis from years to days. What can it do for the groundbreaking Rubin Observatory?

April 28, 2026

AI image processing has sped up analysis of data from NASA’s James Webb Space Telescope from years to mere days or less, ushering in an avalanche of ground-breaking discoveries that may otherwise never have been made. And now, the technology will be used to enhance the quality of images taken by the Chile-based Vera C. Rubin Observatory, the newest astronomy power house, to make them appear as…

NASA wants to use a fleet of MoonFall drones to scout the lunar south pole: 'We believe we can do it'

April 28, 2026

Last month, NASA chief Jared Isaacman ripped off the Band-Aid on the space agency’s back-to-the-moon agenda, calling for a large overhaul of NASA’s Artemis Program. One of his announcements was a speedy series of robotic missions to scout, conduct experiments and prepare…

Sun unleashes 2 colossal X-flares within 7 hours of each other, knocking out radio signals on Earth

April 27, 2026

The first X-flare peaked at 9:07 p.m. EDT on April 23 (0107 GMT April 24) (Image credit: NOAA GOES-19) The sun has certainly woken up! It has fired off not one but two powerful X2.5 solar flares within just 7 hours. Both eruptions came from a sunspot region on the sun’s western limb, AR4419. The first solar flare peaked at 9:07 p.m. EDT on April 23 (0107 GMT April 24), followed by the second at…
