NASA's Nancy Grace Roman Space Telescope, launching in 2026, is expected to find around 100,000 planets beyond our solar system in a single mission — after nearly 30 years of searching, astronomers have confirmed roughly 6,000.

Ordinary Matter Is Just 5 Percent of the Universe. On 30 August NASA Launches a 300-Megapixel Telescope Built to Map the Other 95.

Everything astronomers can see directly — stars, planets, gas, dust, people — accounts for about five percent of the universe. Roughly 27 percent is...

32 years ago this week, 20 fragments of a shattered comet slammed into Jupiter with the force of 300 million atomic bombs — humanity had never watched two Solar System bodies collide, and a NASA probe happened to have a ringside seat

In July 1994, astronomers watched something no human had ever seen: a comet colliding with a planet. Shoemaker-Levy 9 had already been torn apart...

Jupiter’s Great Red Spot is wider than Earth, carries winds above 400 mph and has raged for nearly two centuries — a storm no Category 5 hurricane can match

Earth’s strongest hurricanes last days and peak near 200 mph. Jupiter’s giant anticyclone doubles that speed, spans more than our planet and draws its...

A NASA space telescope is falling out of the sky, and to save it the agency skipped its own contractors and handed the job to a four-year-old startup that had never flown a spacecraft — nine months and $30 million after its own $2 billion rescue program collapsed.

The Neil Gehrels Swift Observatory has spent 21 years as astronomy's first responder, swinging toward exploding stars faster than any other telescope. Now it...

The Hubble Space Telescope launched in 1990 with the most perfectly polished mirror humans had ever made, ground to exactly the wrong shape by one-fiftieth the width of a human hair — a flaw too small to see that blurred every image, until a shuttle crew flew up three and a half years later and fitted the telescope with glasses.

When Hubble reached orbit in 1990, it carried what was called the most perfectly polished mirror humans had ever made — and it was...
