Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.
Want some crazy space phenomena? You don’t have to leave the neighborhood for it.
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 […]
The mission could launch as soon as the 2030s, the researchers said.
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 […]
The upcoming launch of the James Webb Space Telescope is the event of a lifetime.
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.
Already 14 billion miles from the Sun, Voyager 1 is speeding away at 38,000 mph.
The largest moon around our last planet didn’t originate with Neptune. When it comes to the moons of our Solar System, there’s only one planet that doesn’t fit in with our […]
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 […]
On the morning of March 31, 2020, these three worlds will be at their mutual closest in 20 years. For the past few weeks, Mars, Saturn, and Jupiter have all shone […]
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.
Chemical energy, where electrons transition in atoms, powers the reactions we see. But two other types hold more promise than all the rest.
A unique exoplanet without clouds or haze was found by astrophysicists from Harvard and Smithsonian.
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.
When people pick the greatest scientist of all-time, Newton and Einstein always come up. Perhaps they should name Johannes Kepler, instead.
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.
In 2006, Pluto was demoted in a very controversial decision. Unless you ignore nearly all of planetary science, it’ll never be one again.
Gravitation, all on its own, can reveal what’s present in the cosmos like nothing else.
Phobos and Deimos only have two explanations, and neither one adds up.
The most unique interloper into our Solar System has a natural explanation that fits perfectly — no aliens required.
Even at its faintest, Venus always outshines every other star and planet that’s visible from Earth, and then some!
The recently discovered Oort cloud comet, Bernardinelli–Bernstein, has the largest known nucleus: 119 km. Here’s what it could do to Earth.
And the one step we can take to show extraterrestrials we’re figuring it out. Every year, Earth’s meteor showers accomplish two important tasks. This composite photograph shows a large number of […]
NASA is scrapping its Apollo-era launcher platform to make room for new infrastructure that will support upcoming Artemis missions.
On other planets, blue skies and red sunsets aren’t the norm.
Theoretically, we know what happened on the red planet. Here’s how we’ll find out whether we’re right. When it comes to the worlds beyond Earth in our Solar System, it’s only […]
In 1990, we only knew of the planets in our own Solar System. Today, the exoplanet count is more than 5000. Here’s what we’ve learned.
