The new measurement, announced today, was done by an international team of astronomers using the Hubble Space Telescope.

If it's still so useful someone tell me again why we are letting the Hubble die?

Aren't these types of stars called Binary Stars?

The companion, called Sirius B...

Also referred to as "The Pup".

Surely you can't be Sirius (B)! Nice photo on NASA site:

Volume of Earth, mass of two Sols? That is wicked dense.

White dwarfs are involved in explosions called Type Ia supernovas, which are used to measure cosmological distances and the universe’s rate of expansion.

Apparently, it is a close call whether the white dwarf orbiting Sirius is big enough to create a supernova. If so, then it may wipe out all life on earth because it is so close. On the other hand, most of the astronomers say it's not quite big enough.

Howard Stern was interviewed by O'Reilly. He will soon become the highest paid entertainer when he becomes a Sirius Star!!

At c^2 in a super-momentum state, sirius B is about 15 minutes away(105 sec/LY). This is from DeBroglie's equation : u=c^2/v Wanna go?

The companion, called Sirius B, was known to be much hotter. It is the scorching ember of a Sun-like star now called a white dwarf, and it’s the nearest of its kind.

I prefer Dwarfs to be of the "Red" variety...

When Sirius comes around this time of year it always gives me pause for introspection. Sometimes I will look up that star and try to think about what was going on in the world and in my life around 8 1/2 years ago. Somehow that mental exercise helps me to put things in perspective. It helps me clarify things better than making a New Year's resolution can. Does anyone else have thoughts like that or does this sound hopelessly weird or nerdy?

Nearby Star Smaller than Earth, Massive as Sun

Does this sun make my solar system look fat?
