Scientists solve weighty matter of Milky Way mass

Scientists solve weighty matter of Milky Way mass Astronomers said Thursday they had accurately calculated the mass of the Milky Way for the first time, using new data sets that include the weight of dark matter. require(["medianetNativeAdOnArticle"], function (medianetNativeAdOnArticle) { medianetNativeAdOnArticle.getMedianetNativeAds(true); }); In a collaboration between NASA and the European Space Agency's Gaia observation craft, a team of experts calculated our galaxy to be around 1.5 trillion solar masses. Previous estimates put the mass of the Milky Way ranging between 500 billion and 3 trillion times the mass of the Sun.

When NASA sets its sights on a far-away galaxy , there's often a lot to take in. Even if it only appears to be a dim blob, researchers can often combine various observations to determine the galaxy 's size and shape. Normally, they're just there, sitting in space , creating new stars and doing.

When NASA sets its sights on a far-away galaxy , there's often a lot to take in. Scientists now believe that the galaxy is essentially stealing “fuel” to power its energy output from three neighboring galaxies . As the intense gravity sucks up material from the trio of smaller galaxies , the larger central

NASA is getting ready to go hunting — not for a white whale, but for a jellyfish.

In a statement released last week, the agency announced its plans to investigate the distant galaxy ESO 137-001 once it launches its James Webb Space Telescope. The galaxy has earned its "jellyfish" nickname from the long "ribbons of young stars" that trail behind it as it makes its way through the cosmos, looking like "cosmic tentacles," NASA explained.

While it makes for a stunning picture, scientists aren't sure what enables the galaxy to form stars in such a manner. It's been a mystery since we first spotted ESO 137-001 using the Hubble Space Telescope and Chandra X-ray Observatory in 2014 — which is why, once the Webb telescope launches, it will take a closer look at the mysterious galactic cephalopod.

Rock On: NASA releases artsy shots of 2 asteroids NASA has released a pair of artsy shots of two little asteroids. Thursday's picture shows a space rock coming apart at its dusty seams, courtesy of the Hubble Space Telescope. And photos of asteroid Bennu show a giant boulder on the tiny rocky world. The 3D boulder images were taken by NASA's Osiris-Rex spacecraft, flying alongside Bennu.

NASA ’s Spitzer Space Telescope also observed the unique galaxy . The W. M. Keck Observatory was The near-infrared light image of the galaxy (inset) has been colored blue as suggestive of its Measuring galaxies at these extreme distances and characterizing their properties is a main goal of

While its relative proximity to Earth makes it an ideal target for professional astronomers to study its active nucleus in more detail, its big apparent size in the night sky and its brightness also make it a beautiful target for amateur astronomers.

With a long trail of newly-forming stars and hot gases that are slowly leaking out of the galaxy, scientists have a rare opportunity to find out what's causing the leak, Spacereported. This investigation could give us clues about how new stars form, and whether producing too many new stars can actually cause a galaxy to die.

The James Webb Space Telescope, which has experienced setbacks and delays already, is expected to launch in 2021. It will be able to take photographs of ESO 137-001 with much better resolution, and will observe more wavelengths of light to get more information about the galaxy.
