The age of the star-forming knots in the ring is calculated to be 2-8 million years. [6] Stars no older than one million to two million years old are forming closer to the centre of NGC 2445. [ 3 ] Observations of carbon monoxide emission indicate that NGC 2445 still has abundant gas and star formation rates will increase.
The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy.
Studying X-ray and gamma-ray objects with Hubble, as well as Chandra and Compton, gives accurate size and positional data. In particular, Hubble's resolution can often discern whether the target is a standalone object, or part of a parent galaxy, and if a bright object is in the nucleus, arms, or halo of a spiral galaxy. Similarly, the smaller ...
One supernova has been observed in NGC 2444/5, SN 2016bam. The supernova occurred between the two galaxies, about 3.5 arcseconds away from a HII region of NGC 2445. [4] It was a type II supernova which had magnitude 16.1 at discovery. [5] NGC 2445 and NGC 2444 (which lies about one arcminute away) form a pair, known as Arp 143.
NGC 4631 mosaic of two HST images; 7.2′x2′ view. NGC 4631 contains a central starburst, which is a region of intense star formation.The strong star formation is evident in the emission from ionized hydrogen [5] and interstellar dust heated by the stars formed in the starburst. [6]
When our sun dies about 5 billion years from now it might look something like this glowing celestial display which was captured from 4,600 light-years away. Hubble image of a star exploding may ...
The team nicknamed the star system Mothra due to its extreme magnification and brightness. Surprisingly, Mothra has appeared before, detected in Hubble observations nine years ago.
Hubble Space Telescope in the cargo bay of Discovery. STS-31 was launched on April 24, 1990 at 12:33:51 UTC (8:33:51 am EDT, local time at the launch site). A launch attempt on April 10, 1990, was scrubbed at T−4 minutes for a faulty valve in auxiliary power unit (APU) number one. The APU was eventually replaced, and the Hubble Space ...
