The Extremely Large Telescope (ELT) will have a light-collecting power 10 times greater than today’s best telescope.

Even from a single pixel, multiwavelength data taken over time can reveal clouds, icecaps, oceans, continents, and even signs of life.

New telescopes, radio dishes, and gravitational wave detectors are needed for next-generation science. Will the USA lead the way?

The sharpest optical images, for now, come from the Hubble Space Telescope. A ground-based technique can make images over 100 times sharper.

The Hubble Space Telescope, launched in 1990, was originally seen as a colossal mistake. This one image, taken in 1995, changed everything.

The space telescope’s findings challenge the notion of a galaxy brimming with life.

After drastic cuts to the NIH, the FDA, the NSF, and the DOE, NASA science faces down its smallest budget ever. All of society will suffer.

Our scientific instruments are constantly improving, revealing nature’s workings as never before. Without them, we’ll remain in the dark.

In November 1974, astronomers used the radio telescope at Puerto Rico’s Arecibo Observatory to send a hello to the universe.

The most famous Hubble images show glittering stars and galaxies amidst the black backdrop of space. But more was captured than we realized.

There are a number of factors to consider when choosing where to build a telescope. These 3 locations, on their merits, surpass all others.

National Geographic’s first James Webb Space Telescope book shows us the cosmos like never before.

NASA’s space telescopes and observatories bring humanity unrivaled science images and scientific discoveries. Here’s what should be next.

Interferometry gave us a black hole’s event horizon, but that was in the radio. What can we accomplish with a new optical interferometer?

Lasers, mirrors, and computational advances can all work together to push ground-based astronomy past the limits of our atmosphere.

The Vera C. Rubin Observatory in Chile will image the southern sky using the largest digital camera ever built.

Ground-based facilities enable the greatest scientific production in all of astronomy. The NSF needs to be ambitious, and it’s now or never.

“Asking the question of, where did the entire universe come from, is no longer a question for poets and theologians and philosophers. This is a question for scientists, and we have some amazing scientific answers to this question that have defied even the wildest of our expectations.”

More than two years after JWST began science operations, our Universe now looks very different. Here are its biggest science contributions.

Many were hoping that JWST would find the first stars of all. Despite many hopeful claims, it hasn’t, and probably can’t. Here’s how we can.

NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.

Coming from just 280 million years after the Big Bang, or 98% of cosmic history ago, this new, massive galaxy is a puzzle, but not a mirage.

A new SETI study shows how far the field of technosignatures has come.

The detection of two celestial interlopers careening through our solar system has scientists eagerly anticipating more.

The most iconic, longest-lived space telescope of all, NASA’s Hubble, is experiencing orbital decay as the solar cycle peaks. Here’s why.

The “little red dots” were touted as being too massive, too early, for cosmology to explain. With new knowledge, everything adds up.

The JWST’s observations of well-developed galaxies early in universal history may coincide with accepted astronomical theory after all.

With LEDs bringing brighter nighttime lighting than ever before, and thousands of new satellites polluting the skies, astronomy needs help.

NASA’s only flagship X-ray telescope ever, Chandra, still works and has no planned successor. So why does the President want to kill it?

All telescopes are fundamentally limited in what they can see. JWST reveals more distant galaxies than Hubble, but still can’t see them all.
