Hubble Captures Best Ever Image of Triangulum Galaxy | Astronomy

Hubble's detailed image of nearby galaxy

For one, the Triangulum Galaxy is much smaller, with a diameter of just 60,000 light-years compared to the Milky Way's 100,000.

The Hubble Space Telescope has snapped an incredible image of the Triangulum Galaxy, which is 3 million light years from our own Milky Way Galaxy.

The full image contains nearly 25 million stars, and will help scientists study not just the Triangulum Galaxy, but Andromeda and our own. No, seriously, the final image is so huge that you'd never want to wait for it to load on a web page.

But in a new 665-million pixel image taken by the NASA/European Space Agency (ESA) Hubble Space Telescope, the spiral galaxy's billions of stars are brightly showcased.

The borders of individual Hubble images trace the jagged edge of the mosaic, which spans 19,400 light-years across.

The partial shutdown , which began December 22, has cut off funding to the Treasury Department. The shift from the White House comes as officials prepare for an extended shutdown .

ESA says the Triangulum image is the second-largest ever released by Hubble and will help astronomers better understand how stars form and evolve.

"My first impression on seeing the Hubble images was, wow, that really is a lot of star formation", project lead Julianne Dalcanton of the University of Washington said in a statement. Striking areas of star birth glow bright blue throughout the galaxy, particularly in lovely nebulas of hot, ionized hydrogen gas like star-forming region NGC 604 in the upper left.

"Under excellent dark-sky conditions, the Triangulum Galaxy can be seen with the naked eye as a faint, blurry object in the constellation of Triangulum (the Triangle), where its ethereal glow is an exciting target for amateur astronomers", Hubble added on its website. He captured the view from Long Island's North Fork (accessible from New York City by commuter rail) two weeks ago. Astronomer Steven Bellavia, an engineer at Brookhaven National Laboratory, coincidentally sent me an image he took of the galaxy with a 71mm refracting telescope and 20 megapixel astronomy camera over the course of two hours.

As always, this is your reminder to look at space!
