A floating platform the size of Rome collapsed off of Antarctica.

Scientists have long puzzled over how Mars, a cold and dry planet, was once warm enough to support liquid water.

Which is good, because if they do, they violate the cosmological principle. In theory, the Universe should be the same, on average, everywhere. A simulation of the large-scale structure of […]

Introducing the Deep Space Food Challenge.

Do the laws of physics place a hard limit on how far technology can advance, or can we re-write those laws?

An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn’t dark matter, but merely neutron stars.

There are so many problems, all across planet Earth, that harm and threaten humanity. Why invest in researching the Universe?

Figuring out the answer involved a prism, a pail of water, and a 50 year effort by the most famous father-son astronomer duo ever.

The discovery could help astronauts find better ways to grow food in space.

For the past 150+ years, the big ones have all missed us. But at some point, our good luck will run out.

Steel tires may be better for the planet and could replace rubber.

Dark energy is one of the biggest mysteries in all the Universe. Is there any way to avoid “having to live with it?”

NASA is scrapping its Apollo-era launcher platform to make room for new infrastructure that will support upcoming Artemis missions.

We’ve only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.

Each December, the Geminid meteor shower puts on a show for skywatchers across Earth. With a new Moon at 2023’s peak, it’ll be outstanding!

Every observation out into deep space is also a look back in time. Whenever you observe an object, you aren’t viewing it in its present state. When one of Jupiter’s moons […]

The first supernova ever discovered through its X-rays has an enormously powerful engine at its core. It’s unlike anything ever seen.

The psychology of alien contact largely revolves around the concept of “otherness.” We need to learn to be comfortable around strange things.

Humans are more likely to have “first contact” with an advanced alien civilization, according to a recent NASA-funded paper.

The search for worlds outside our solar system has just turned up a planet, TOI-2257 b, with a truly extreme orbit.

Galaxies can have regions both hotter and colder than the background radiation of the Universe. When we talk about the depths of space, we get this picture in our heads […]

From before the Big Bang to the present day, the Universe goes through many eras. Dark energy heralds the final one.

With 1550 distinct type Ia supernovae measured across ~10 billion years of cosmic time, the Pantheon+ data set reveals our Universe.

If we were born trillions of years in the future, could we even figure out our cosmic history?

Watch the plasma slide down the prominence like a roller coaster! Our Sun, despite it’s outward appearance as a perfectly hot sphere, is anything but uniform. When take a closer look […]

Scientists track down a puzzling early burst of oxygen on Earth.

National Geographic’s first James Webb Space Telescope book shows us the cosmos like never before.

By the end of the decade, we may discover one million black holes. A large enough mass in a compact volume inevitably forms a black hole. Both inside and outside the […]

Many contrarians dispute that cosmic inflation occurred. The evidence says otherwise.

There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren’t typical?
