    The comet 46P/Wirtanen, which passes Earth every 5.4 years, was one of three comets discovered by Carl Wirtanen in 1948 at the Lick Observatory in California. This orbit will be one of the closest comet orbits to Earth since the 1950s, according to Space.com. The comet 46P will likely not have a large observable tail because of its relatively small size, according to Space.com. It measures 0.68 miles in diameter, one-tenth the size of the popular Halley's Comet. Currently, 46P is a small blueish object in the night sky. The comet will be passing in the Southern sky, near the...

    The...wave is thought to form as the lower atmosphere flows over mountains on Venus' surface. ... Just after entering orbit around Venus in 2015, the Akatsuki orbiter observed a bow-shaped feature in the upper atmosphere over several days. Curiously, the bright structure - which stretched for 10,000km - remained stationary at the altitude of Venus' cloud tops. This is difficult to reconcile with what we know about Venus' thick upper atmosphere, in which clouds streak by at 100 metres per second (m/s). The clouds travel much faster than the slowly rotating planet below, where a Venusian day lasts longer than...
  • Scientists push back against Harvard 'alien spacecraft' theory [Oumuamua]

    11/07/2018 10:22:54 AM PST · by Olog-hai · 34 replies
    A scientific paper led by two researchers at Harvard University made a splash this week by claiming that a cigar-shaped rock zooming through our solar system may have been sent by aliens. The researchers noted in a pre-print of the article that it was an “exotic scenario,” but that “Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization.” Oumuamua, the first interstellar object known to enter our solar system, accelerated faster away from the Sun than expected, hence the notion that some kind of artificial sail that runs on sunlight — known as...

    Blue asteroids are rare, and blue comets are almost unheard of. An international team led by Teddy Kareta, a graduate student at the University of Arizona's Lunar and Planetary Laboratory, investigated (3200) Phaethon, a bizarre asteroid that sometimes behaves like a comet, and found it even more enigmatic than previously thought. Phaethon sets itself apart for two reasons: it appears to be one of the "bluest" of similarly colored asteroids or comets in the solar system; and its orbit takes it so close to the Sun that its surface heats up to about 800 degrees Celsius (1,500 degrees Fahrenheit), hot...

    Scientists have uncovered the truth about a mysterious space rock called Oumuamua which has been hurtling through Earth’s solar system and was spotted last year.A group of acclaimed astronomers, including members from NASA, the European Space Agency and the German Max Planck Institute for Astronomy, released a report this week on the origins of the cigar-shaped asteroid which was first observed in October 2017. The name Oumuamua is Hawaiian for “messenger from afar arriving first” and was named by the site who first spotted it. According to the report, “a fast moving object on an unbound orbit was discovered close...

    Want to see a comet whizzing by Earth? A great chance to catch one of these celestial visitors is overnight tonight, when Comet 21P/Giacobini-Zinner will be best visible in binoculars or a telescope. The comet, also known as "21P," will make its closest approach to Earth at around 2:30 a.m. EDT Monday (630 GMT). The bright-green comet should reach a visual magnitude of 6.5 to 7, according to EarthSky.org. This makes 21P almost bright enough to see with the naked eye — but not quite.

    More than 200 people across Missouri and seven other states spotted a fireball meteor last night light as it lit up the Midwestern sky, KMOV reports. The American Meteor Society posted observer accounts and several videos of the sighting to its website Tuesday. "It was super bright..." said Lisa B. in Ellisville, Missouri, who filed a report with the group. "We said, what IS that?!? Omg it's a fireball, I have to get my camera. Then tried to open my camera and the trail was all that was left." Some observers said the meteor appeared to break up into several...

  • Astronomy Picture of the Day -- Draconid Meteors Over Spain

    NASA ^ | October 19, 2011 | (see photo credit)
    Explanation: What are those streaks in the sky? They're meteors from the Draconids meteor shower that peaked earlier this month. The above composite image captured numerous meteor streaks over 90 minutes above the Celtic ruins of Capote in Badajoz province, Spain. The particles that caused these meteors were typically the size of a pebble and were expelled long ago from the nucleus of comet 21P/Giacobini-Zinner. Most of the above meteors can be traced back to a single radiant emanating from the constellation of the Dragon (Draco). Reports from this year meteor shower indicate that the Draconids were unusually good this...

    Comet Watch UK ^ | 2018 | editors
    Giacobini-Zinner’s return in 2018 is a promising one as it passes the Earth at a distance of 0.39 au. In June, 2018, 21p will be observable from modest sized telescopes sitting in the constellation of Cygnus reaching a brightness of magnitude 11 by month end. Although for many in the northern hemisphere, the sky will not reach true astronomical darkness all month. Between 17-21 June, the comet will skim past the ‘Mexico’ region of the North America nebula making for a nice widefield shot for photographers (again battling the twilight). The comet will then brighten rapidly through July and August by which time...

    Viewing the Incredible Hulk with the naked eye may be a little tricky. Because the comet got so close to the sun and broke up from solar heat, it's rapidly fading from view. Also, thunderstorms and clouds in various parts of the country may impede vision of the comet. However, experts don't rule out another eruption in the coming days, which could make the comet brighter in the night sky. Additionally, Paul Chodas, the manager for the Center for Near-Earth Object Studies at the Jet Propulsion Laboratory, told Live Science the comet may be visible later in August ― around...

    To date, every comet humanity has seen inside the Solar System has come from the Solar System, whether it's the Kuiper Belt or the billions of comets believed to make up the Oort Cloud. Now, however, it looks like astronomers might have found a comet of interstellar origin. They've used Hawaii's Pan-STARRS 1 telescope to track C/2017 U1, an object with a very eccentric, hyperbolic orbit (that is, moving quickly enough to escape gravitational pull) that wasn't connected to the Sun. The trajectory suggests that it's a comet which escaped from a nearby star, rather than something knocked out a...

    The Hubble Space Telescope captured a view of Comet C/2017 K2 (PANSTARRS), called K2 for short, as it came in from out beyond Saturn's orbit, 1.5 billion miles from the sun. As it approaches the sun and the temperature rises from minus 440 degrees Fahrenheit, the comet is developing a fluffy cloud of dust, called a coma, which surrounds its frozen body. While the comet's nucleus appears to be just 12 miles across, the coma stretches 10 times Earth's diameter. According to a statement from NASA, K2 likely began its journey in the spherical Oort Cloud surrounding the solar system,...

    Every object in our Solar System that takes the plunge from out beyond Neptune to our inner reaches, where the rocky planets lie, will become a comet. As it nears the Sun, its ices melt, creating the tails we associate with them, and also creating a debris path that can create meteor showers if they cross Earth's orbit. For thousands of years, the most consistent, spectacular meteor shower has been the Perseids, created by Comet 109P/Swift-Tuttle. At its incredibly large size (26 kilometers across) and speed, it contains nearly 30 times the energy of the asteroid strike that wiped out...

    When it was discovered on July 19th, 2017 by the All Sky Automated Survey for Supernovae (ASAS-SN) system, Comet O1 ASAS-SN was at a faint magnitude +15.3 in the constellation Cetus. In just a few short days, however, the comet jumped up a hundred-fold in brightness to magnitude +10, and should be in range of binoculars now. Hopes are up that the comet will top out around magnitude +8 or so in October, as it transitions from the southern to northern hemisphere. Never heard of ASAS-SN? It’s an automated sky survey hunting for supernovae in both hemispheres, with instruments based...

    Yet another Jovian fireball? On May 26th, amateur astronomers recorded a rare impact flash in Jupiter's north polar region. Jupiter just got beaned for the sixth time (that we know about)! On the evening of May 26th, between 19:24.6 and 19:26.2 Universal Time, Sauveur Pedranghelu, a French amateur from Corsica, detected an impact flash live on video in Jupiter's north polar region. The flash was very brief, lasting only about 0.7 second, and displayed two brightness peaks. A bright dot — about the size of Europa when seen in transit — marked the site of impact at latitude 51° north...

    The American space agency says that one object is a massive comet, but has so far been unable to identify the other NASA recently spotted two massive space objects hurtling towards Earth. While the American space agency has pinpointed one as a comet, the other has left it slightly more baffled. The comet is set to fly close to Earth this week, but the mystery object isn't expected to make an appearance until February. The object, dubbed "2016 WF9", was detected by NASA's asteroid- and comet-hunting NEOWISE project on 27 November 2016. It is roughly 0.3 to 0.6 miles (0.5...

    Seeing Comet C/2016 U1 NEOWISE fly by would be a rare opportunity for skygazers because the celestial body won't likely pass by Earth for the next thousands of years. Unlike short period comets such as Halley's, a comet which passes by our planet every 75 to 80 years, it would take C/2016 U1 NEOWISE far longer time before it gets to visit this region of the solar system again. ...
