2022 was another busy year in the realm of science, with groundbreaking stories spanning space, materials, medicine, and technology.
Dead whales inspire a way to find extraterrestrial life on Mars.
JADES JWST z 13
Leaving Hubble in the dust, JWST has officially seen a galaxy from just 320 million years after the Big Bang: at just 2.3% its current age.

The most common element in the Universe, vital for forming new stars, is hydrogen. But there's a finite amount of it; what if we run out?
Compared to Earth, Mars is small, cold, dry, and lifeless. But 3.4 billion years ago, a killer asteroid caused a Martian megatsunami.
We have less time than you might think.
By studying the dwarf galaxy Wolf-Lundmark-Melotte ~3 million light-years away, JWST reveals the Universe's star-forming history firsthand.

We cannot afford to dream about living on other worlds while we continue to destroy ours.
moon base
From astrobiology to geology, a Moon base could serve as a laboratory unlike anything on Earth.
At 1,600 light years away, the black hole is practically in our cosmic backyard.
It's rare that one single image packs so much beauty and science simultaneously. This Hubble view of a nearby star-forming region has both.

We're used to scientists telling us about the math and physics behind astronomical events. But what does studying space make us feel?
Astronomers have been looking for radio waves sent by a distant civilization for more than 60 years.
All across the Universe, planets come in a wide variety of sizes, masses, compositions, and temperatures. And most have rain and snow.
gaia black hole
The ESA's Gaia mission just broke the record for closest black hole by over 1,000 light-years. Is there an even closer one out there?

Science is for everyone, even those possessing strongly held beliefs that seem to conflict with the best available evidence.
IceCube just found an active galaxy in the nearby Universe, 47 million light-years away, through its neutrino emissions: a cosmic first.

We know the Universe is expanding, but scientists don't agree on the rate. This is a legitimate problem.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we're woefully unprepared.
In 1995, Hubble peered at the Pillars of Creation, forever changing our view. Now in 2022, JWST completes the star-forming puzzle.
The stars circle each other every 51 minutes, confirming a decades-old prediction.
Most exoplanets have been found around single stars via the transit method. But binary star systems might contain even more of them.
universe rotate
Early relics and late-time objects give incompatible results for the expanding Universe. This independent anomaly intensifies the problem.
