The Hubble Space Telescope searches the universe to understand how planets, stars, and galaxies form. Recently, it captured ...

The Horsehead Nebula, also known as Barnard 33, ... And by studying it, astronomers have learned the stellar nursery has already given birth to young stars, some even with protoplanetary disks.

More protoplanetary nebula in the Monoceros constellation. It is part of a binary star system, where one member is ejecting the hydrogen gas in the post-AGB phase.

Protoplanetary nebula IRAS 13208-6020 Image Credit: ESA/Hubble & NASA. Protoplanetary nebulae are objects with extremely short life span (less than 10,000 years). This is one of the final stages ...

NASA and the European Space Agency's Hubble telescope captured a rare photo of the Calabash Nebula, a protoplanetary nebula formed from a dying star that's 1.4 light years long and approximately ...

At that time, the sun was surrounded by a disk of material known as a protoplanetary nebula that was gradually dissipating as it coalesced into the planets we know and love.

Newborn stars are surrounded by disks of gas and dust within which planets are born, known as protoplanetary disks. In the Orion Nebula, the brightest and most massive stars emit intense ...

A dying star has been spotted coughing up a toxic mix of gases in a spectacular new photo from the Hubble Space Telescope. The newly released image shows the Westbrook Nebula, also known as PK166 ...

This work in progress is situated in the Orion Nebula, a luminous cloud of interstellar gas and dust about 1,500 light-years away. Its star is about 1 million years old—a baby, in astronomy terms.
