How to find Messier 48?

Keep your binoculars handy and use the two points of reference you’ve just learned to find our next target – Messier 48. By connecting Epsilon and Alpha as the base of an imaginary triangle with the top pointed southwest, aim your binoculars at the apex and behold one very nice – and very bright – open star cluster. Discovered by Charles Messier in 1771 and also cataloged as NGC 2548, you might even be able to distinguish this stellar field as a hazy spot unaided from a dark sky location. With an estimated age of about 300 million years, you’ll see a very large group of about 50 stars which can resolve into as many as 80 members in larger telescopes. When you see M48, you can thank Caroline Herschel for fixing Messier’s position mistake on this one!

What is the name of the star that is about 2000 years away from Earth?

To the east of Gamma is R Hydrae. Now here is one classy variable star! Located about 2000 years away from Earth, R Hydrae ’s changes take a period of 389 days to happen, but they happen in a big way. The magnitude of this crazy star jumps from a very dim and telescopic only 11.0 to an easy unaided eye 3.2! R is the third Mira-type variable discovered and may have been noted as early as 1662 by Johannes Hevelius. R Hydra is also special because it has a “declining period” – it has changed its times by 100 days in the last couple of hundred years. So what’s happening? A helium shell is building up around the exterior – just waiting for the day to reach a critical mass and ignite, creating more carbon and oxygen. This is called a “helium shell flash” and it signals the end of life for the giant star. Eventually the layers will just expand into space and the carbon-oxygen core will shine as a white dwarf star. Look around while you’re there… Because you just might spot a companion!
