James Webb space telescope is ready to launch On December

James Webb Space Telescope, will launch on December 18 on an Ariane 5 rocket.

James Webb space telescope will launch on December 18, NASA said Wednesday. Space observatory, which is a joint project by NASA, the European Space Agency and the Canadian Space Agency, will blast off on an Ariane 5 rocket from Spaceport in French Guiana. currently stowed at Northrop Grumman's facilities in Redondo Beach, California, where it is awaiting shipping. Astronomers hope that the James Webb Space Telescope will supercharge the discovery of alien worlds.

Stephen Hawking's theory about black holes may have been proven right.

Turns out, black holes exert pressure on all space surrounding them. Hawking had predicted that black holes emit radiation in 1974, implying that the objects have temperature. In addition, Hawking claimed that black holes slowly shrink over time if no accumulation of gases (accretion) takes place. Scientists from the University of Sussex - Professor Xavier Calmet and Folkert Kuipers published their findings in Physical Review D. The researchers were probing the event horizon (a black hole's boundary) of a black hole when they made the startling discovery. They were looking an entropy at the event horizon of the black hole, which is essentially the chaos embedded into any physical object and its progression from calm to mayhem. While reading the calculations, the scientists kept running into an additional figure which they couldn't explain. It took them months to figure out that it was actually caused by pressure around the black hole. This pres...

Web results Water vapour detected on huge Jupiter moon Ganymede for 1st time

Astronomers have uncovered the first evidence of water vapour in the atmosphere of Jupiter's moon Ganymede using Hubble space telescope. NASAs Hubble Telescope reveals first evidence for water vapour in Jupiters moon Ganymede. According to the study published in the journal Nature Astronomy on Monday, the water vapour forms when ice from the moon's surface turns from solid to gas. Previous studies have offered circumstantial evidence that Ganymede, contains more water than all of Earth's oceans, NASA said. However, temperatures there are so cold that water on the surface is frozen solid, according to the US space agency. Ganymede's ocean would reside roughly 160 kilometres below the crust, therefore, the water vapour would not represent the evaporation of this ocean. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapour. In 1998, Hubble's Space Telescope Imaging Spectrograph took the first ultraviolet (UV) im...
