The grainy image of a “super-Jupiter” is a sign of what’s to come as the telescope’s exoplanet observations ramp up.

In the days after the mega-telescope started delivering data, astronomers reported new discoveries about galaxies, stars, exoplanets and even Jupiter.

In 2019, the Event Horizon Telescope released a historic image of a supermassive black hole in another galaxy. The follow-up — an image of Sagittarius A* — shows it shimmering at the center of our own.

Robots are about to venture into the sunless depths of lunar craters to investigate ancient water ice trapped there, while remote studies find hints about how water arrives on rocky worlds.

We might have a past faint sun to owe for life’s existence. This has consequences for the possibility of life outside Earth.

Over the past decade, researchers have completely rewritten the story of how gas giants such as Jupiter and Saturn form. They’re now debating whether the same process might hold for Earth.

After a search of neutron stars finds preliminary evidence for hypothetical dark matter particles called axions, astrophysicists are devising new ways to spot them.

Brown dwarfs such as “The Accident” are illuminating the murky borderlands that separate planets from stars.

These ultrabright flashes have recently been tracked for days, upending ideas about the cataclysms that create them.
