Hubble finds evidence of galaxy star birth regulated by black-hole fountain

Astronomers have uncovered a unique process for how the universe's largest elliptical galaxies continue making stars long after their peak years of star birth. NASA's Hubble Space Telescope's exquisite high resolution and ultraviolet-light sensitivity allowed the astronomers to see brilliant knots of hot, blue stars forming along the jets of active black holes found in the centers of giant elliptical galaxies.

Gravitational constant appears universally constant, pulsar study suggests

Gravity, one of the four fundamental forces of nature, appears reassuringly constant across the Universe, according to a decades-long study of a distant pulsar. This research helps to answer a long-standing question in cosmology: Is the force of gravity the same everywhere and at all times? The answer, so far, appears to be yes.

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.
