NGC 7023, also known as the Iris Nebula, is a reflection nebula in the constellation Cepheus. It's a bright nebula that's visible in the northern sky.

The sky will get a colourful nebula, and the remains of the explosion become a small, dense star. While we will not be around ...

An curved arrow pointing right. The Orion Nebula is a giant gas cloud 1,344 light years away. It's also a cosmic factory for producing new stars. Astronomers recently observed over 900 small ...

First, the basics: A nebula is a giant cosmic cloud of gas and dust. The word 'nebula' comes from Latin, meaning "little mist." Before telescopes existed, astronomers considered all such faint ...

The modeling allowed the astronomers to estimate that roughly 6,000 years have elapsed since the dying star, then a red giant, ejected the molecular gas that envelopes the nebula. The SMA data also ...

The stunning red image of Tarantula Nebula was captured by NASA's Hubble Telescope. It is a star-forming region in the Large Magellanic Cloud (LMC) galaxy. This 100 million-year-old globular cluster ...

The team's findings indicate that roughly 6,000 years have elapsed since the dying star, then a red giant, ejected the molecular gas that envelopes the nebula. The SMA data also reveal high ...

A nebula is a giant cloud of dust and gas in space. Some nebulas come from the gas and dust thrown out when a dying star explodes. Others are regions where new stars are beginning to form.

Explore the breathtaking beauty of the cosmos with these seven rare images of star clusters, captured by NASA's Hubble Space ...

The discovery was made possible using the Very Large Telescope (VLT) in Chile, operated by the European Southern Observatory (ESO) ...
