A coronal mass ejection on another star has been witnessed in its entirety for the first time, revealing that when these violent outbursts take place on young stars, they pack enough energy to potentially kickstart the chemistry of life on any orbiting planets.
Young stars can be much more tumultuous than older stars. Stellar physics predicts that in our sun’s formative years it was throwing…
James Webb Space Telescope spots the haunting Red Spider Nebula with 3-light-year-long legs
October 31, 2025
Out in the cosmic landscape, planetary nebulas would offer the perfect Halloween doors to knock on.
They’re spooky tricksters in their names, as they have nothing to do with planets at all and are rather the gory scenes of stars dying. The term “planetary…
Enormous black hole unexpectedly found in tiny galaxy
October 30, 2025
An unexpected monster black hole was found hiding inside one of the Milky Way’s tiniest neighbors, rewriting what scientists thought they knew about how small galaxies hold themselves together.
Segue 1 is an ultra-faint dwarf galaxy located about 75,000 light-years…
Mercury will reach its greatest eastern elongation on Oct. 29, marking one of the best evenings to see the planet this fall as it appears farthest from the sun’s glare in the twilight sky.
As the solar system’s innermost planet, Mercury travels an extremely tight orbit around our parent star, with an average separation of under 36 million miles (58 million kilometers). As a result, it…
Earth’s moon is a treasure trove of resources. Space agencies around the world are planning missions to access and use lunar volatiles, which include hydrogen, water, helium, carbon dioxide, and carbon monoxide, in order to produce fuel sources, breathable air, and…
An innovative technique for measuring the force acting on individual grains of sand could help scientists uncover how winds have shaped the surface of Mars.
The method, developed by researchers at the State University of Campinas in Brazil, uses images of dune surfaces to…
Black Holes and Their Creation Through Mergers
October 29, 2025
Scientists have “heard” the symphony of two newborn black holes — each created when its respective parent black holes crashed together and merged. One of those collision events, in fact, was the first of its kind.
The detection of the baby black holes and information about the four parent black holes that forged them came courtesy of ripples in spacetime, or gravitational waves…
1st samples ever collected from the moon's far side could help reveal where Earth got its water
October 29, 2025
Fragments of a rare type of meteorite have been found in the sample of material brought back from the lunar far side by China’s Chang’e 6 mission, and they could help shed light on the origin of Earth’s water.
The meteoritic debris found among the 1,935.3…

'The solar system on demand': HEO Robotics aims to push spacecraft imaging deep into the final frontier
October 28, 2025
An Australian firm leading the way in providing images of spacecraft in low Earth orbit is making moves to expand its capabilities to higher orbits — and possibly, in the long run, to solar system destinations.
HEO, also known as HEO Robotics, has made a splash with sensational images of spacecraft in low Earth orbit (LEO) that were taken by other spacecraft, or “non-Earth imaging”…
