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 ...

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 ...

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 ...

Variable stars aren’t just cosmic curiosities — they’re living laboratories for understanding stellar physics. From Deneb’s unpredictable pulsations to century-old classification efforts, these stars ...

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 ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a peculiar cataclysmic variable star. The newly found system, designated SDSS J134441.83+204408.3 (or J1344 for ...

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 ...
