Astronomers have found what could be the first-ever sighting of a planet forming while still in the midst of a dust cloud surrounding a star. The object, which orbits the star HD 100546, is only 335 light-years from Earth and …

Globular clusters are spherical groupings of stars tightly bound by gravity. While these objects are usually 12 to 13 billion years old, a new study has found that clusters can appear to be vastly different ages, depending on the behavior …

A new type of galaxy nicknamed “green bean galaxies” has been identified and they are some of the rarest objects in the known universe. The nickname comes from the galaxies’ appearance: they glow with intense light generated by the ionized …

Astronomers have now observed that the dust disc orbiting a brown dwarf contains millimeter-sized solid particles – the same “grains” found in the denser discs surrounding new stars.The new data suggests that rocky planets, such as Earth, may be more …

Astronomers have discovered a quasar with the most massive outflow ever seen. Quasars are bright galactic centers powered by supermassive black holes, and many of them accelerate the material around them, throwing it out a high speed in a process …

Astronomers have discovered that a dwarf planet in our solar system named Makemake has no atmosphere. The object, which orbits in the outer solar system, was expected to have an atmosphere similar to another dwarf planet, Pluto, but new observations …

Astronomers have identified what is “very probably” a relatively close-by planet hurtling through space – not orbiting a star. The European Southern Observatory used its Very Large Telescope and the Canada-France-Hawaii Telescope to study the object, which it calls the …
