Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!

Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.

Ingenuity is remarkable. But these 5 exploration ideas are revolutionary. Telescopes are our initial tools for revealing and studying foreign worlds. Hubble images of Mars, particularly around the regions with […]

And what can it teach us about our Solar System’s earliest days? In many ways, astronomy is unique among the sciences. In every other field, you have the ability to design […]

For some reason, when we talk about the age of stars, galaxies, and the Universe, we use “years” to measure time. Can we do better?

Our Solar System’s outer reaches, and what’s in them, was predicted long before the first Oort Cloud object was ever discovered.

Life finds a way — particularly if it has a moon.

A new model of the Antikythera mechanism reveals a “creation of genius.”

The rings are raining down onto the planet, and disappearing surprisingly fast. 4.5 billion years ago, our Solar System first formed. Protoplanetary disks, which all solar systems are thought to […]

Catch Saturn at its biggest and brightest, and view its rings while you still can. Right now, in Earth’s skies, Saturn appears at its biggest and brightest. A view of tonight’s […]

For consumers of festive beverages, the news is bad: this holiday season, Guinness may not be on tap and glass for bottling wine is scarce. Climate disasters, like British Columbia’s floods, have further weakened already […]

We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]

Jupiter’s mysterious auroral events are caused by vibrating waves of plasma.

Francisco José de Goya y Lucientes is often labeled a quintessential Spanish artist, but his allegiance may well have lied with the French Enlightenment instead.

The massive craft could carry 100 humans to Mars and revolutionize space exploration.

Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]

NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.

The far side of the Moon is incredibly different from the Earth-facing side. 63 years later, we know why the Moon’s faces are not alike.

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 […]

In a world of rising cynicism, a celebration of our capacity to create, adapt, and thrive.

Want some crazy space phenomena? You don’t have to leave the neighborhood for it.

The upcoming launch of the James Webb Space Telescope is the event of a lifetime.

When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.

Even though the leftover glow from the Big Bang creates a bath of radiation at only 2.725 K, some places in the Universe get even colder.

It started with a bang, but won’t end with one. Instead, it will “rage against the dying of the light” like nothing you’ve ever imagined.

Based on the atoms that they’re made out of, the innermost planet should always be the densest. Here’s why Earth beats Mercury, hands down.

No matter how your year went, Hubble’s views of the Universe never disappoint. Year after year, Hubble’s telescopic views are unparalleled. Saturn, its rings, and 5 of its moons are […]

And why, even at its faintest, it always outshines every other star and planet. If you’ve been looking to the west after sunset recently, you may have noticed that there’s one […]

Chemical energy, where electrons transition in atoms, powers the reactions we see. But two other types hold more promise than all the rest.

The mission could launch as soon as the 2030s, the researchers said.
