    Messier 100, also known as M100, NGC 4321 and LEDA 40153, is located approximately 50 million light-years away in the constellation of Coma Berenices.This galaxy is one of the brightest members of the Virgo Cluster, a group of about 1,300 (and possibly up to 2,000) galaxies.Its apparent magnitude of 10.1 means that, while it can be seen through small telescopes, it will appear only as a faint patch of light. Larger telescopes can resolve more details of the galaxy.The galaxy was discovered on March 15, 1781 by the French astronomer Pierre Méchain, Charles Messier’s fellow comet hunter who discovered eight...
  • Weird star system has double binary stars and wonky planetary nursery

    There is a star system 146 light years from Earth that is quite strange. At its centre is a set of binary stars, and around that loops another binary pair. In between is a ring of dust and gas that’s set at a very odd angle. The dust and gas of this system, which is called HD 98800, are part of a disc that may be forming planets in a kind of cosmic nursery. Instead of lying on the same plane as the central stars, this disc’s orbit is perpendicular to that. The full system is even more confusing (see...

    Astronomers have revealed details of mysterious signals emanating from a distant galaxy, picked up by a telescope in Canada. The precise nature and origin of the blasts of radio waves is unknown. Among the 13 fast radio bursts, known as FRBs, was a very unusual repeating signal, coming from the same source about 1.5 billion light years away. Such an event has only been reported once before, by a different telescope. "Knowing that there is another suggests that there could be more out there," said Ingrid Stairs, an astrophysicist from the University of British Columbia (UBC). "And with more repeaters...

    Dr. Tremblay said: "This is the first direct evidence that white dwarfs crystallise, or transition from liquid to solid. It was predicted fifty years ago that we should observe a pile-up in the number of white dwarfs at certain luminosities and colours due to crystallisation and only now this has been observed....The Sun itself will become a crystal white dwarf in about 10 billion years."

    First spotted in 2007, FRBs are one of the most intriguing mysteries in astrophysics. They appear all over the sky, and astronomers aren’t sure what causes them. n early testing during July and August, before it began full operations, CHIME spotted 13 FRBs. Prior to this, astronomers had between 50 and 60 examples. The more FRBs that astronomers find, the greater the chance they can start to pin down their origin. CHIME also detected only the second known FRB that repeats, meaning that the radio flashes re-appear at the same point in the sky. It saw the repeater pop up...

    Extraordinary Claims Need an Extraordinary Cosmos.

    Although the flyby occurred at 12:33 a.m. ET on Tuesday, the spacecraft is so far from Earth that the “phone-home” signal didn’t reach us until about 10:30 a.m. ET. Mission scientists were relieved about the success because there was only one chance to get it right as New Horizons screamed past Ultima at 31,500 miles per hour. This incredible feat was possible because thousands of operations on the spacecraft worked in sync. “We’ve just accomplished the most distant flyby,” mission operations manager Alice Bowman said. “This science will help us understand the origins of our solar system.” New Horizons has...

    Only a week before its expected meeting with Kuiper Belt object (KBO) Ultima Thule on New Year's Day, NASA's New Horizons spacecraft has not been able to detect the predictable and consistent variations in reflectivity — or ‘light curve' in the jargon of astronomers — that accompany all celestial objects in orbit near a bright star. "It's really a puzzle," agreed Alan Stern, NASA's New Horizons principal investigator, cited by Gizmodo. Southwest Research Institute mission scientist Marc Buie suggested that the rotational point of Ultima Thule could currently be aligned directly toward the NASA spacecraft as it approaches. From that...

    At the furthest reaches of the solar system, 2019 will start off with exploration. NASA has given the final green light to its New Horizons spacecraft for a January 1st flyby of Ultima Thule, an object in the Kuiper Belt around a billion miles beyond Pluto. It will be the most distant planetary flyby in human history. Before giving the okay, NASA wanted to make sure that it wasn't passing up any other opportunities for either study or disaster in the area—rings, small moons, and anything else that a probe like New Horizons might want to observe. Pushing through the...

    NASA's New Horizons spacecraft has beamed home another glimpse of the distant, icy body it will zoom past just three weeks from now. The small object Ultima Thule swims amid a sea of distant stars in the new composite photo, which New Horizons snapped with its Long Range Reconnaissance Imager (LORRI) camera at around midnight EST (0500 GMT) on Dec. 1. At the time, the probe was 24 million miles (38.7 million kilometers) from Ultima and more than 4 billion miles (6.4 billion km) from Earth New Horizons took the picture 33 hours before performing a record-setting engine burn to...

    Following its discovery in October 2017, ‘Oumuamua was the subject of popular speculation about a possible non-natural origin. Its highly elongated shape and the fact that no coma was observed strengthened this hypothesis for some, as these are uncharacteristic of asteroids and comets.A recent paper by Harvard Smithsonian Center for Astrophysics researchers Dr. Shmuel Bialy and Professor Abraham Loeb has also suggested the possibility that ‘Oumuamua is a deliberate construction.The scientists argued that the slight, unexpected acceleration observed for this object could be caused by pressure from sunlight as ‘Oumumua swung around the Sun. Their hypothesis is that the object...

    Harvard scientists reexamined the bizarre, interstellar space object known as “Oumuamua,” which rocketed through our solar system late last year, resurrecting the possibility that it may be an alien probe. Academics and scientists were quick to write off the cigar-shaped object as a previously unknown type of bolide – a comet or asteroid – propelled in a highly unusual manner, but their observations are once again, being challenged. Oumuamua, which means “a messenger sent to reach out in advance,” was first observed by Robert Weryk at the Pan-STARRS 1 telescope in Hawaii. He measured the object to be several hundred...

    `Oumuamua, pronounced oh-MOO-ah-MOO-ah – is moving away from the sun faster than expected. The Hubble Space Telescope made the discovery, in cooperation with ground-based telescopes... The measured gain in ‘Oumuamua’s speed is tiny, these astronomers said. Plus, our sun is still trying to drag `Oumuamua back; that is, the sun’s gravity is still slowing down the object, though not as fast as predicted by celestial mechanics. Marco Micheli of the European Space Agency led the team that explored several scenarios to explain ‘Oumuamua’s faster-than-predicted speed. The most likely explanation is that `Oumuamua is venting material from its surface due to...

    Full title: ESO observations show first interstellar asteroid is like nothing seen before. For the first time ever astronomers have studied an asteroid that has entered the Solar System from interstellar space. Observations from ESO's Very Large Telescope in Chile and other observatories around the world show that this unique object was traveling through space for millions of years before its chance encounter with our star system. It appears to be a dark, reddish, highly-elongated rocky or high-metal-content object. The new results appear in the journal Nature on 20 November 2017.

    To recap, when `Oumuamua was first observed on October 19th, 2017, by astronomers using the University of Hawaii’s Panoramic Survey Telescope and Rapid Response System (Pan-STARRS), the object (then known as C/2017 U1) was initially believed to be a comet. However, subsequent observations revealed that it was actually an asteroid and it was renamed 1I/2017 U1 (or 1I/`Oumuamua). Follow-up observations made using the ESO’s Very Large Telescope (VLT) were able to place constraints on the asteroid’s size, brightness, composition, color and orbit. These revealed that `Oumuamua measured some 400 meters (1312 feet) long, is very elongated, and spins on its axis...

    Astronomers around the world are trying to track down a small, fast-moving object that is zipping through our solar system. Is a comet? An asteroid? NASA's not sure. The space agency doesn't even know where it came from, but it's not behaving like the local space rocks and that means it may not be from our solar system. If that's confirmed, NASA says "it would be the first interstellar object to be observed and confirmed by astronomers." NASA says astronomers are pointing telescopes on the ground and in space at the object to get that data. For now, the object...
