Open Cluster

Will the Sun make a planetary nebula when it dies?. In around 7 billion years, we expect the Sun to run out of fuel, dying in a planetary nebula/white dwarf combination. Is that for certain?.

November's full Beaver Moon will be the final of four consecutive supermoons in 2024.

Using data from the Hubble and Chandra space telescopes, scientists have determined that dark matter ghosted through the wreckage of two colliding galaxy...

Westerlund 1 is the biggest and closest "super" star cluster to Earth. New data from NASA's Chandra X-ray Observatory, in combination with

This new image from the NASA/ESA Hubble Space Telescope features the globular cluster NGC 1841, which is found within the Large Magellanic Cloud.

The observations offer a window into the past to better understand how globular clusters may have formed.

Have you ever noticed how some stars, when arranged, can form shapes in the night sky? Trace asterisms along with us!

A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at NGC 2210, a globular cluster situated in the Large Magellanic Cloud.

Astronomers used the combined powers of the Hubble and Webb telescopes to take a portrait of colliding clusters of galaxies, called the Christmas Tree Galaxy...

This enormous structure could help explain processes close to the dawn of time—or it could be a random cosmic fluke

Our best understanding of the universe is rooted in a cosmological model known as LCDM. The CDM stands for cold dark matter, where most of the matter in the universe isn't stars and planets, but a strange form of matter that is dark and nearly invisible. The L, or lambda, represents dark energy. It is the symbol used in the equations of general relativity to describe the Hubble parameter, or the rate of cosmic…

X-ray satellites have collected data on the merging of two galaxy clusters, and the resulting computations are mind-breaking.

The launch of a revolutionary satellite that will reveal celestial objects in a new light and the

The Japan Aerospace Exploration Agency is expected to launch an X-ray satellite to study extreme cosmic objects and a lunar lander nicknamed the "Moon Sniper...

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics.

NASA's Hubble Space Telescope has been captivated by a dazzling cosmic spectacle as it gazes upon this star-studded globular cluster NGC 6652.

Space is a big place, but that doesn't prevent galaxies from colliding with their nearby neighbors, especially as they grow over billions of years and larger galaxies consume smaller ones.

Scientists at the Leibniz Institute for Astrophysics Potsdam (AIP) and Boston University have successfully established a connection between the rotation rates of stars in star clusters and those outside them, so-called field stars, enabling the ages of the latter to be derived.

Prime Day is the perfect time to buy a telescope that's always been out of your price range. The Celestron StarSense dropped to $400 today.

Data collected with the Very Large Telescope shows a vast region of gas and dust resembling a celestial cat with a cluster of young stars right under its nose.
