For decades, scientists puzzled over why Uranus seemed colder than expected. Now, an international research team led by the University of Houston has solved the mystery: Uranus emits more heat than it gets from the Sun, meaning it still carries internal warmth from its ancient formation. This revelation rewrites what scientists know about the ice giant’s history, strengthens the case for NASA’s upcoming mission, and offers fresh insight into the forces shaping not only other planets, but also Earth’s future climate.

A new study led by University of Houston researchers, in collaboration with planetary scientists worldwide, suggests Uranus does have its own internal heat — an advance that not only informs NASA’s future missions but also deepens scientists’ understanding of plan...

A stunning new image of a cosmic jet has helped astronomers unlock the mystery behind the usually bright emission of high-energy gamma rays and neutrinos from a peculiar celestial object. The source is a blazar—a type of active galaxy powered by a supermassive black hole devouring matter a the heart of a galaxy. They have captured what looks like the mythical “Eye of Sauron” in the distant universe and may have just solved a decade-long cosmic puzzle.

The researchers made a discovery that will help in understanding how a seemingly slow-moving blazar, known as PKS 1424+240, could be one of the brightest sources of high-energy gamma rays and cosmic neutrinos ever observed. The work is published in the journal Astronomy & Astrophysics.

Located billions of light-years away, the bl...

This NASA/ESA Hubble Space Telescope image captures incredible details in the dusty clouds of a star-forming factory called the Tarantula Nebula. Most of the nebulae Hubble images are in our galaxy, but this nebula is in the Large Magellanic Cloud, a dwarf galaxy located about 160,000 light-years away in the constellations Dorado and Mensa.

The Large Magellanic Cloud is the largest of the dozens of small satellite galaxies that orbit the Milky Way. The Tarantula Nebula is the largest and brightest star-forming region, not just in the Large Magellanic Cloud, but in the entire group of nearby galaxies to which the Milky Way belongs.

The Tarantula Nebula is home to the mos...

Future technology could one day allow a miniature, laser-propelled spacecraft — no heavier than a paperclip — to travel to a nearby black hole, according to a bold new proposal published on Thursday (Aug. 7).

The ambitious mission would aim to test the limits of Albert Einstein’s theory of general relativity in one of the universe’s most extreme environments. It may sound like the plot of a sci-fi novel, but to cosmologist Cosimo Bambi, this idea is rooted in real physics — and could be achievable within our lifetime.

“It may sound really crazy, and in a sense closer to science fiction,” Bambi, who is a researcher in the department of physics at Fud...
