Measuring Fast radio bursts

Fast radio bursts (FRBs) are brief spurts of radio emission, lasting just one-thousandth of a second, whose origins are mysterious.

Hubble Sees Spiral in Andromeda

Hubble Sees Spiral in Andromeda

The Andromeda constellation is one of the 88 modern constellations and should not be confused with our neighboring Andromeda Galaxy. The Andromeda constellation is home to the pictured galaxy known as NGC 7640.

Our Solar System May Have Formed in 4 Million Years

Scientists from MIT and their colleagues have estimated the lifetime of the solar nebula -- a key stage during which much of the solar system evolution took shape.


A Black Hole Feeding Frenzy That Breaks Records

A Black Hole Feeding Frenzy That Breaks Records

A giant black hole ripped apart a nearby star and then continued to feed off its remains for close to a decade, according to research led by the University of New Hampshire.

Measuring The Expansion of the Universe Hints at New Physics

Astronomers have just made a new measurement of the Hubble Constant, the rate at which the universe is expanding, and it doesn't quite line up with a different estimate of the same number.

Hubble Captures Brilliant Star Death in "Rotten Egg" Nebula

The Calabash Nebula, pictured here - which has the technical name OH 231.8+04.2 - is a spectacular example of the death of a low-mass star like the sun.


Tracing The Cosmic Web

Tracing The Cosmic Web

Galaxies in the universe trace patterns on very large scales; there are large empty regions (called "voids") and dense regions where the galaxies exist.


NGC 6334 and NGC 6357: Celestial Cat Meets Cosmic Lobster

NGC 6334 and NGC 6357: Celestial Cat Meets Cosmic Lobster

NGC 6334 is located about 5500 light-years away from Earth, while NGC 6357 is more remote, at a distance of 8000 light-years. Both are in the constellation of Scorpius (The Scorpion), near the tip of its stinging tail.

Classifying NGC 4861 In Canes Venatici

The lesser-known constellation of Canes Venatici (The Hunting Dogs), is home to a variety of deep-sky objects -- including this beautiful galaxy, known as NGC 4861. Astronomers are still debating on how to classify it.

Struggle to Escape Distant Galaxies Creates Giant Halos of Scattered Photons

Astronomers led by David Sobral and Jorryt Matthee, of the Universities of Lancaster in the UK and Leiden in the Netherlands have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape them.
