How NASA’s Roman Telescope Will Measure the Ages of Stars

Stars are born spinning rapidly, but slow down over billions of years. (Our 4.5-billion-year-old Sun spins about once per month.) After about one billion years, stars of the same mass and age will spin at the same rate. Therefore, if you know a...

Three-Year Study of Young Stars with NASA's Hubble Enters New Chapter

ULLYSES, the largest Hubble program ever, collected information about almost 500 young stars over a three-year period. It aims to help researchers gain new insights about the stars’ formation, evolution, and impact on their surroundings.

NASA's Hubble Finds that Aging Brown Dwarfs Grow Lonely

A Hubble telescope survey has found that brown dwarfs—objects smaller than stars but bigger than planets—live a lonely life as they age. Over time they lose the companion brown dwarf that was born alongside them and the objects drift their...

Cheers! NASA’s Webb Finds Ethanol, Other Icy Ingredients for Worlds

A new Webb study of two protostars, so young that they have not yet formed planets, has found a variety of molecules ranging from relatively simple ones like methane to complex compounds like acetic acid (familiar to cooks as an ingredient in...

NASA’s Webb, Hubble Telescopes Affirm Universe’s Expansion Rate, Puzzle Persists

The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. Some scientists suggested that Hubble observations are wrong due to some creeping...

Space Telescope Science Institute (STScI): Nearly 400 years after Galileo first observed the heavens through a telescope, we continue to seek answers to age-old questions about the universe. And while the technology has evolved over the centuries, the inquiry remains essentially the same: What's out there, where did it come from, and what does it mean?

At the Space Telescope Science Institute (STScI), we're working hard to study and explain the once-unimaginable celestial phenomena now made visible using Hubble's cutting-edge technology. In the course of this exploration we will continue to share with you the grace and beauty of the universe, because the discoveries belong to all of us.
