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 ...

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 ...

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 ...

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 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 ...

New research offers the most precise measurements yet of pulsating Cepheid stars, which may hold clues about the immense size and scale of our universe. Cepheids are a type of variable star that ...

In a recent astronomical revelation, scientists have detected a galactic-scale “heartbeat” rhythm pulsating within stars billions of light-years away from Earth. This entrancing cosmic rhythm offers a ...

The positions in the table below reflect the Variable Stars South's position overall, domestically, within their sector, and in various subject areas based on their Share. Each position links to the ...
