• Scientists Determine The Diameter Of The Disc Of The Milky Way Is 200000 Light Years Across - The Inquisitr

    A new paper has just been published by the National Astronomical Observatories of Beijing (NAOC) and the Instituto de Astrof iacute;sica de Canarias (IAC) which lays out the claim that the diameter of the disc of the Milky Way is so massive that it would take us 200,000 light years to properly cross it from one side to the other. But as large as our galaxy is, it is worthwhile remembering that the disc of our neighbor galaxy, Andromeda, measures in at a whopping 220,000 light years across.The Milky Way is a type of galaxy that is known as a spiral galaxy, and these galaxies are known for having extremely thin discs. It is around these discs that you will find the vast majority of the galaxy rsquo;s stars, as Phys.org report. And because the discs themselves are so very thin, normally if you move beyond a certain point from it you are unlikely to find very many stars.

  • Black Holes Cluster At The Center Of The Milky Way: Chandra X-ray Observatory (NASA) - Sunrise News

    The newly discovered cluster consists of stellar mass black holes lurking at the focal point of the Milky Way galaxy. These black holes are approximately five to thirty times the mass of the Sun. The cluster as observed at a distance of three light years. It is at a relatively shorter length on the cosmic scales.Our Galaxy #8217;s focal point is known as the Sagittarius A (Sgr A ). The recent study indicates that a massive population of the black holes approximately twenty thousand in number could collect around the Sagittarius A . This Chandra data analysis is first of its kind.

  • NASA astronomers discovered numbers of black holes in center of Milky Way - Daily Enterpriser

    Researchers at the United States space company NASA have actually come across a collection of black holes hiding in the facility of our Milky Way galaxy. The impressive exploration was used the information beamed back by the NASA;s Chandra X ray Observatory.The freshly found great void bounty includes stellar mass black holes, which normally consider in between 5 to 30 times the mass of the Sunlight. These recently recognized black holes were located within 3 light years #8211; a reasonably brief range on planetary ranges #8211; of the supermassive great void at our Galaxy #8217;s facility referred to as Sagittarius A (Sgr A ).

  • LISA Observatory Might Be Able To Detect 'Dozens' Of Milky Way Binaries - The Inquisitr

    It won rsquo;t be another 15 years or so before the Laser Interferometer Space Antenna (LISA) observatory is launched into outer space, but astronomers are already excited about the potential discoveries its launch could yield. A new study, in fact, suggests that LISA might be able to detect ldquo;dozens rdquo; of binaries, or pairs of gravitationally bound, orbiting compact objects, in Milky Way rsquo;s globular clusters.A news release published in EurekAlert described the study published Friday by a team of Northwestern University researchers, which suggests that our galaxy might be teeming with binaries, and that LISA would be able to spot these pairings of objects. The binaries might include a variety of pairings, including combinations that include black holes, neutron stars, and white dwarf stars alongside more conventional counterparts. Interestingly, the researchers also predicted that LISA could find binaries that have their own peculiarities that set them apart from those that formed in isolation.

  • Stellar mass black holes swarm in Milky Way's core - Astronomy Now Online

    The Chandra X ray Observatory has found direct evidence for up to 10 stellar mass black holes and, by statistical extension, thousands more lurking within a few lightyears of Sagittarius A , the supermassive black hole at the center of the Milky Way.Previous studies of stellar dynamics indicated a large number of stellar mass black holes #8211; suns with five to 30 times the mass of the Sun #8211; could be expected to migrate inward over the galaxy #8217;s multi billion year history. The Chandra observations represent the first observational evidence supporting that scenario.

  • Milky Way is hiding thousands of black holes - IT-Online

    Astronomers have discovered evidence for thousands of black holes located near the centre of our Milky Way galaxy using data from NASA;s Chandra X ray Observatory.This black hole bounty consists of stellar mass black holes, which typically weigh between five to 30 times the mass of the Sun. These newly identified black holes were found within three light years #8211; a relatively short distance on cosmic scales #8211; of the supermassive black hole at our Galaxy #8217;s centre known as Sagittarius A (Sgr A ).

  • Stephen Hawking's Hunt For Alien Life Gets Big Boost With Expanded Survey Of Milky Way Stars - Tech Times

    The Breakthrough Listen Initiative, created by Russian inventor Yuri Milner, Hawking, and others, has the objective of collecting deep space data to find signals of alien life."We believe that life arose spontaneously on Earth," Hawking said nbsp;in July 2015 during the launch of the project. "So in an infinite universe, there must be other occurrences of life."

  • Milky Way Blues — Listen to the Sound of our Galaxy Rotating

    This musical expression lets you "hear" how our Milky Way Galaxy rotates. Radio telescopes observe different spectral emission lines to probe different phases of gas (atomic, molecular, ionized) in our Galaxy. Astronomers measure the Doppler shifts of these lines to determine gas velocities along the path that the telescope is pointing. To turn one of these observations into musical notes, the measured gas velocities are mapped to a pentatonic minor blues scale. Every note you hear and circle you see represents gas that is either coming toward us (high notes and blue color) or going away from us (low notes and red color). Different gas phases are played by different instruments and shown by different colored borders on the circles. Each observation is represented by a line showing where the telescope was pointing and the positions of the circles along a line show the locations of the gas in the Galaxy. The star symbol shows the location of the Sun. The intensity of the emission coming from the gas is heard as longer note durations and shown as larger circles. With every new measure, the lines swing around to new observations. Putting it all together, the variation of musical pitches heard in the Milky Way Blues portrays the motion of gas as it orbits around the center of our Galaxy.
