WASHINGTON (CyHAN)- GK Persei
, a nova ushering in the 20th century, and the Firework nebula it produced may hold the keys to uncovering the secrets of stars, specifically their violent death in a spectacular explosion, known as a nova or a supernova.
Initially, opinion was divided between those who thought that Anderson had simply made an embarrassing mistake, possibly the misidentification of another field star during a hurried observation by an ageing observer, and those who thought there might be more to Anderson's report, pointing out that he had an international reputation for discovery through his detection of two bright novae, Nova Aurigae 1891 and Nova Persei
1901, and more than 50 variable stars, as well as independently discovering Nova Aquilae 1918 and comet 17P/Holmes in 1892.
I will review the properties of open clusters rich in RSGs, such as chi Persei
and NGC 7419, and introduce the RSG population of Stephenson 2, the second most massive young cluster known in the Milky Way, which contains the largest collection of RSGs.
Washington, January 25 ( ANI ): A team of astronomers has reconstructed the journey of the gas emitted by a powerful explosion of GK Persei
- that has not stopped growing and astonishing ever since - in 3D.

Mr Griffiths and his team caught the comet with a Canon EOS 350D digital camera, but say it can be spotted using a pair of binoculars if people look to the north east below the W-shaped constellation of Cassiopeia, close to the bright star Alpha Persei
Mercedes Richards and her colleagues from Pennsylvania State University in State College recorded radio waves from flares spewing from two nearby star systems, Beta Persei
and V711 Tauri.
Algol, or [beta] Persei
, is appropriately one of that class of stars called variable, whose magnitude vacillates between 2.

Gore had thus made an independent discovery of Nova Persei
Although the first light echo to be seen was around Nova Persei
in 1901, SN1987A is a much more spectacular example.
Only one previous nova has been seen to occur inside a planetary nebula - Nova Persei
