Hubble captures awe-inspiring PHOTO of Triangulum galaxy that spans 19,400 light-years As the holiday season draws to a close, the Hubble telescope has provided one truly massive parting gift: an immensely detailed photo of one of our galactic neighbors that spans 19,400 light-years across.

Triangulum, also known as Messier 33 or NGC 598, is part of the Local Group - a collection of more than 50 galaxies, including the Milky Way, that are bound together by gravity.

While it is possible to observe the Triangulum Galaxy under excellent dark-sky conditions, the human eye will only see it as a faint, blurry object with an ethereal glow in the Triangulum (the Triangle) constellation.

The mosaic of the Triangulum Galaxy showcases the central region of the galaxy and its inner spiral arms. Its diameter is only 60 thousand light years in comparison with 200 thousand the galaxy Andromeda or 100 thousand the milky Way.

Jaguar Land Rover to cut 5000 United Kingdom jobs
Jaguar Land Rover (JLR) is expected to announce plans to cut thousands of jobs as part of a £2.5bn plan to reverse losses. Ninety per cent of its vehicles are diesel-powered, although it has been investing in new electric and hybrid vehicles.

The Hubble Space Telescope's mind-blowing new image of the Triangulum Galaxy is nearly as enormous as the galaxy itself.

In the past, star-formation histories in the Local Group have been measured one galaxy at a time, often using different analysis techniques. But it's undergoing extreme star formation, perhaps 10 times more intense than Andromeda, according to the release.

Hubble, which is run by NASA and the European Space Agency, was used to take a panoramic survey of Triangulum in order to better understand how it formed.

"In contrast to the two larger spirals, the Triangulum Galaxy doesn't have a bright bulge at its center and it also lacks a bar connecting its spiral arms to the center", the statement said. New stars form at a rate of approximately one solar mass every two years.

Eight House Republicans Buck Trump, Vote For Bill To Reopen Gov't Agencies
Democrats are also working to sway some moderate and skeptical Republicans to abandon Trump on the wall. Trump bolted after House Speaker Nancy Pelosi told him that more wall funding just wasn't in the cards.

The Andromeda Galaxy was mapped by Hubble in 2015, creating the sharpest and largest image of this galaxy and the largest Hubble image ever.

The new Hubble image shows two of the four brightest of these regions in the galaxy: NGC 595 and NGC 604. Astronomers hope that the new image, along with previous surveys taken of the Andromeda and Milky Way galaxies, will help them gain a deeper understanding of stellar evolution in the Local Group and beyond.

Many other Hubblecast episodes are also available.

Eight European countries agree to take the 49 migrants at sea
Malta last week allowed the boats to shelter near its coasts from the bad weather but would not let them disembark the migrants. Another 78 will be allowed to stay in Malta, while 44 Bangladeshi migrants will be repatriated.
