Supermassive black holes can produce jets soon after tearing apart a star, then fire up again hundreds or thousands of days later when their feeding rate drops to about 2% of the Eddington limit. That same threshold is known to trigger jets from much smaller black holes in the Milky Way.

Extreme radiation may have helped create unusually massive black hole seeds, while dense surrounding gas allowed them to grow dozens of times faster than black holes can today. The simulated objects closely resemble the Little Red Dots seen by Webb. If correct, they could solve the mystery of how enormous black holes formed so soon after the Big Bang.

Dark features on the enormous Sputnik Planitia glacier appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Computer models show that nitrogen could melt at the glacier’s base and travel upward like fluid through small conduits. The finding reveals that Pluto may be much more geologically active than its frozen appearance suggests.

No majority backed the standard cosmological model, a leading explanation for dark matter, or any single theory of quantum gravity. One area of stronger agreement stood out: 68% said the Big Bang does not necessarily represent the beginning of time. Researchers say the divisions show just how alive and unsettled the frontiers of physics remain.

After accounting for the ages of the stars that produce these explosions, researchers found signs that cosmic expansion may actually be slowing. They also argue that the apparent acceleration changes with direction, which would be difficult to explain with dark energy. Other cosmologists dispute the conclusion, setting up a major test for upcoming observatories.

Simulations suggest a roughly 320-meter asteroid struck the Martian moon at an angle, throwing debris around the entire world without breaking it apart. New observations from ESA’s Hera spacecraft support the scenario and indicate that Deimos is surprisingly porous and fragile.

Some refuges may be no larger than a footprint, while one hardy fungus could even withstand limited exposure to sunlight.

The powerful new observatory will probe cosmic expansion, the history of the universe, and distant exoplanets.

Their 10-day Orion mission also carried them farther into space than anyone in history.

The result weakens some modified-gravity explanations and strengthens the case that dark matter is behind the universe’s mysterious missing mass.

Because the stars trace the galaxy’s gravity, researchers used the stream to estimate how much invisible dark matter surrounds it and how that matter is distributed. The breakthrough offers astronomers a promising new way to investigate one of the universe’s greatest mysteries.

The collisions produced quark-gluon plasma, the ultra-hot matter believed to have filled the cosmos shortly after the Big Bang. Even more intriguingly, the particles left behind reveal the shape of the nuclei that created them, offering a new way to probe both nuclear physics and the Universe’s earliest moments.

That hidden population could make some of these galaxies three to four times more massive than previous estimates. The finding makes it even harder to explain how enormous, mature galaxies formed so soon after the Big Bang. It could also suggest that planets around low-mass stars were more common in the early universe than scientists realized.

In some systems, those flares mysteriously fade with every return. Researchers now think the key may be stars that were already spinning extremely fast before being captured. That rapid rotation could explain both the fading flares and how the stars ended up in such extraordinarily tight black hole orbits.
