Using the Indian Astronomical Observatory (IAO) in Hanle, India, astronomers have observed a globular cluster known as NGC 7006. Results of the study, presented December 9 on the arXiv pre-print ...

The constellation Leo, containing the bright star Regulus (α Leonis), is visible in the southwest after sunset. R Leonis, a Mira-type variable star and the first such star identified in Leo, is ...

Astronomers using the Swiss 1.2-metre Euler telescope at ESO’s La Silla Observatory in Chile have found a new type of variable star. The discovery was based on the detection of very tiny changes in ...

Looking like a glittering cosmic geode, a trio of dazzling stars blaze from the hollowed-out cavity of a reflection nebula in a new image from NASA's Hubble Space Telescope. The triple-star system is ...

First detected more than four centuries ago, highly evolved stars known as Mira variables have long been observationally neglected by most of the professional astronomical community. That’s even ...

One of the best places to study stars is inside “open clusters”, which are groups of stars that formed together from the same material and are bound together through gravity. Open clusters act as ...

In a groundbreaking development, a team of astronomers, in collaboration with citizen scientists, has uncovered a new and exciting type of exploding star, GOTO0650, marking a major achievement in both ...

Astronomers discover 13 new symbiotic stars in Gaia DR3 and help close a historic gap between theory and observation.

Using ESO’s Very Large Telescope Interferometer, astronomers from France and Brazil have detected a huge cloud of dust around a star. This observation is further evidence for the theory that such ...

This NASA Hubble Space Telescope image shows a triple-star star system. NASA, ESA, G. Duchene (Universite de Grenoble I); Image Processing: Gladys Kober (NASA/Catholic University of America) A ...

We present the first results from Citizen ASAS-SN, a citizen science project for the All-Sky Automated Survey for Supernovae (ASAS-SN) hosted on the Zooniverse platform. Citizen ASAS-SN utilizes the ...
