Arguably, a hobby’s greatest benefit is derived from its rewards. I’ve been an avid backyard astronomer for 60 years. I still recall the night in 1963 when my high school friend Ray Gerbi showed me ...

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. Subscribe to our ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
