Astronomers unveil a distant protogalaxy connected to the cosmic web

A team of astronomers has discovered a giant swirling disk of gas 10 billion light-years away - a galaxy-in-the-making that is actively being fed cool primordial gas tracing back to the Big Bang. The finding provides the strongest observational support yet for what is known as the cold-flow model of galaxy formation.

The ghost of a dying star

This extraordinary bubble, glowing like the ghost of a star in the haunting darkness of space, may appear supernatural and mysterious, but it is a familiar astronomical object: a planetary nebula, the remnants of a dying star. This is the best view of the little-known object ESO 378-1 yet obtained and was captured by ESO's Very Large Telescope in northern Chile.

Cassiopeia's hidden gem: The closest rocky, transiting planet

A star in the constellation Cassiopeia has a planet in a three-day orbit that transits, or crosses in front of its star. At a distance of just 21 light-years, it is by far the closest transiting planet to Earth, which makes it ideal for follow-up studies. Moreover, it is the nearest rocky planet confirmed outside our solar system.

New Milky Way map reveals stars in our galaxy move far from home

Astronomers have created a new map of the Milky Way that provides the first clear evidence of migration of stars throughout our galaxy. The study, which determined that 30 percent of stars have traveled across the galaxy, is bringing a new understanding of how stars are formed and travel throughout the Milky Way.

Dense star clusters shown to be binary black hole factories

The merger of two black holes is one of the most sought-after observations of modern astronomy. The first observatories capable of directly detecting gravitational waves will begin observing the universe later this year. When these waves rolling in from space are detected on Earth for the first time, astrophysicists predict astronomers will 'hear', through these waves, five times more colliding black holes than previously expected.
