NASA's Juno spacecraft has zipped past Jupiter's poles, watched its Great Red Spot churn, and visited its largest moon.

Black holes are among the most energetic objects in the Universe. But its immense mass generates a gravitational field so intense that not even light can escape from it. So is it possible that such an advanced alien civilization could use a black hole as a massive source of energy? Scientists say yes.

William Shatner is preparing for a trip to space aboard Jeff Bezos' Blue Origin rocket, according to reports. TMZ first reported that the actor who played Captain Kirk on "Star Trek" is expected to blast off on an upcoming October civilian flight in the New Shepard capsule. It has not yet been announced who will join him.

There's a monstrous hole in the universe. Long ago, a star blew up with extreme force and obliterated everything in its path. It even swept minuscule particles of space dust out of its way -- but in a surprising turn of events, that space dust collected, collapsed and eventually gave birth to a bunch of baby stars.

Dubbed 2021 SG, the asteroid flew close to the planet on September 16, but because it came from the direction of the Sun, scientists didn't see it coming.

The James Webb Space Telescope will be 100 times as powerful as the Hubble. Here’s what it will see.

In 1951, the Aerobee-19 rocket launch proved it was possible to send creatures similar to humans to space and bring them back to Earth alive.

Yesterday, we looked at “Untitled Earth Sim 64,” a science fiction comedy based on the idea that Earth is a messed up simulation — created by entities that are in themselves simulations. And maybe their simulators were in turn simulated… And so forth. The problem is, where’s the original? Surprisingly, perhaps, there is a physics theory that offers an answer: The universe simulated itself:

In 1994, the Comet Shoemaker-Levy 9 (SL9) impacted Jupiter, which had captured the comet shortly before (and broken apart by its gravity). The event became a media circus as it was the first direct observation of an extraterrestrial collision of Solar System objects. The impact was so powerful that it left scars that endured for months and were more discernible than Jupiter's Great Red Spot.

About 100 years ago, on May 15, 1921, multiple fires broke out in electricity and telegraph control rooms in several parts of the world, including in the US and the UK. In New York City, it was from a switch-board at the Brewster station that quickly spread to destroy the whole building, and in Sweden, operators at Karlstad exchange first experienced equipment malfunction and faint smoke, then after a period of quiet the main fire started, leading to extensive equipment damage, studies say.

One of SpaceX's oldest rockets launched on a historic 10th flight, carrying the first stack of Starlink satellites into space in more than two months before sticking a landing at sea to cap the successful mission.

Caltech astronomer and Pluto killer Mike Brown claims he has found evidence of a potential planet in the Kuiper Belt roughly 100 billion miles from Earth.

A new startup has created the world's first gas station in Low Earth Orbit (LEO), which will extend the lives of all of the satellites that will be going to space very soon!

Analyzing observations of an X-ray flare and fitting the data with theoretical models, UArizona astronomers documented a fatal encounter between an unlucky star and an intermediate-mass black hole.

Breathtaking detail.

The first crewed mission to China's new space station is in the books. A spacecraft carrying Nie Haisheng, Liu Boming and Tang Hongbo touched down safely in the Gobi Desert in Inner Mongolia today (Sept. 17) at 1:34 a.m. EDT (0534 GMT; 1:34 p.m. Beijing time) today, bringing the historic Shenzhou 12 mission to an end.

To get us to Mars and beyond, a team of students from around the world has a plan involving lunar rovers mining ice and a space station between the Earth and the moon.

If the idea of sending humans to Mars is a romantic one, the reality of it is a bucket of cold water. Going to Mars is hard. Something like half of all missions have failed for one reason or another, but adding humans into the mix makes things far harder.

A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers.

Ten billion years ago, well before the formation of our solar system, a gargantuan explosion threw out vast amounts of highly energetic light. A star died in a dazzling supernova, and, though it happened so long ago, the flash was only seen in 2016 and vanished shortly thereafter. But if you missed it then, worry not: We’ll be able to see the blast again.
