Science never stops for NASA, but space observations and researches, regardless of seasonal or special occasions, the space agency still likes to celebrate holidays. Last week, NASA's fast-approaching celebration took the opportunity to show a very special snapshot captured by the Hubble Space Telescope.
The image provides a look of a distant star known as RS Puppis in all its brilliant glory. Stars and the accompanying mass powder cloud show that NASA's species are a "feast of wreath", but this is a picture that can appreciate Scrooge's.
NASA says that the star is lit for several weeks, but the average brightness is 15,000 times the Sun's. Mass burning balls are about 200 times bigger than our stars and ten times massive. Cepheid is classified as a variable star, that is, its brightness changes constantly.
"Light from the Ceauseum shines with brightness," says NASA. "Hubble drew a series of photographs of a cloud that swept through the cloud to a phenomenon known as light echo, although the light was faster enough to spread the space between Earth and the Moon within a few seconds, but the Nebula is so great that the reflected light can actually take pictures with the nebula. "
NASA has been able to accurately estimate its distance from the Earth, thanks to the unique refined properties of the star and the richness of its surroundings. The RS Puppis is thought to be about 6,500 light years, and NASA relies on a margin of only one percent.
This photo is a reminder of how Hubble has done some of the most striking things even when it's rapidly moving away from three full decades. For these astronomers, the last worker and his advanced age do not seem to prevent us from seeing the miracle of being able to see us.
