Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn't the only force at work.

Hubble Views Galaxy NGC 5023 on Edge

This Hubble Space Telescope image shows an edge-on view of the spiral galaxy NGC 5023. Due to its orientation we cannot appreciate its spiral arms, but we can admire the elegant profile of its disk.

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide.

Using data from orbiting observatories, including NASA's Spitzer Space Telescope, and ground-based facilities, an international team of astronomers has discovered an outburst from a star thought to be in the earliest phase of its development.

More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered.

A Grand Extravaganza of New Stars

This dramatic landscape in the southern constellation of Ara (The Altar) is a treasure trove of celestial objects.

Researchers wanting to know more about the influences of multiple stars on exoplanets have come up with a new case study: a planet in a four-star system.

Using NASA's Chandra X-ray Observatory, astronomers have found that the growth of galaxies containing supermassive black holes can be slowed down by a phenomenon referred to as cosmic precipitation.

A handful of new stars are born each year in the Milky Way, while many more blink on across the universe. But astronomers have observed that galaxies should be churning out millions more stars, based on the amount of interstellar gas available.

Dust plays an extremely important role in the universe - both in the formation of planets and new stars.

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered regions where certain organic molecules somehow endure the intense radiation near the supermassive black hole at the center of galaxy NGC 1068, also known to amateur stargazers as M77.

Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time.

This week an international team of astronomers reports the first multiple-star system to be observed during the earliest stage of formation.

Video: Riding Light

In our terrestrial view of things, the speed of light seems incredibly fast. But as soon as you view it against the vast distances of the universe, it's unfortunately very slow.

Cassiopeia A, or Cas A for short, is one of the most well studied supernova remnants in our galaxy. But it still holds major surprises.

Black Hole Chokes on a Swallowed Star

A five-year analysis of an event captured by a tiny telescope at McDonald Observatory and followed up by telescopes on the ground and in space has led astronomers to believe they witnessed a giant black hole tear apart a star.

A New View of Galaxy M82

An international team of astronomers led from Chalmers has used the giant radio telescope LOFAR to create the sharpest astronomical image ever taken at very long radio wavelengths.

If you sweep a laser pointer across the Moon fast enough, you can create spots that actually move faster than light. Anyone can do it.

By analyzing the light of hundreds of thousands of celestial objects, Johns Hopkins astronomers from the Sloan Digital Sky Survey (SDSS) have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars.
