Our galaxy is due for a catastrophic collision, study says



A mysterious luminous object in the sky, dubbed "The Cow", was captured in real time by telescopes around the world. Astronomers believe it could be the birth of a black hole or a neutron star, or a new class of objects.

An illustration describes the detection of a rapid blast repeated by a mysterious source 3 billion light years from Earth.

This is the illustration of an artist out of the farthest object of the solar system still observed, 201

8 VG18 – also known as "Farout". The pink hue suggests the presence of ice.

The Comet 46P / Wirtanen will pass within 7 million miles of the Earth on December 16th. His ghostly green coma is Jupiter's size, though the comet itself is about three-quarters of a mile in diameter.

This mosaic image of the Bennu asteroid is composed of 12 PolyCam images collected on December 2 by the OSIRIS-REx probe from a 15-mile radius.

These images reveal the final stage of a union between pairs of galactic nuclei in the disordered nuclei of colliding galaxies.

A radio picture of hydrogen gas in the Little Magellanic Cloud. Astronomers believe that the dwarf galaxy is slowly dying and will eventually be consumed by the Milky Way.

Further evidence of a supermassive black hole at the center of the Milky Way galaxy has been found. This visualization uses data from simulations of orbital gas movements that swirl about 30% of the speed of light on a circular orbit around the black hole.

Do you think it's a bat? This giant shadow comes from a bright star that is reflected against the dusty disk that surrounds it.

Hey, Bennu! NASA's OSIRIS-REx mission, aimed at meeting the primitive asteroid Bennu, is postponing the images as it approaches its December 3 target.

These three panels reveal a supernova before, during and after 920 million light-years from Earth (left to right) occurred. The supernova, nicknamed iPTF14gqr, is unusual because although the star was huge, its explosion was quick and weak. The researchers believe that this is due to a companion star that has subtracted its mass.

This is an illustration of an artist of how a Neptune-sized moon would be in orbit around the giant ecoplanet of Kepler-1625b gas in an 8,000-year-old starlight system. It could be the first exomoon ever discovered.

The illustration of an artist from Planet X, who could model the orbits of external objects of the smaller solar system extremely distant as the 2015 TG387.

This is the concept of an artist of what SIMP J01365663 + 0933473 might seem. It has 12.7 times the mass of Jupiter, but a magnetic field 200 times more powerful than Jupiter. This object is 20 light years from Earth. It's on the dividing line between being a planet or being a brown dwarf.

The Andromeda galaxy cannibalized and cut off the once large M32p galaxy, leaving behind this compact galaxy residue known as M32. It is completely unique and contains a wealth of young stars.

Twelve new moons have been found around Jupiter. This graph shows various groupings of moons and their orbits, with those discovered recently shown in bold.

Scientists and observers from around the world have been able to track down a high-energy neutrino in a galaxy with a supermassive black hole and rapidly rotating in the center, known as the blazar. The galaxy is located to the left of Orion's shoulder in its constellation and is about 4 billion light years from Earth.

& # 39; Oumuamua, the first interstellar visitor observed to our solar system, is shown in an artist's illustration.

The planets do not appear out of nothing – but require gas, dust and other processes not fully understood by astronomers. This is the impression of an artist of what the "infant" planets seem to form around a young star.

These negative images of the 2015 BZ509, which is circled in yellow, show the first known interstellar object that has become a permanent part of our solar system. The exo-asteroid was probably introduced into our solar system by another star system 4.5 billion years ago. It then stabilized in a retrograde orbit around Jupiter.

A close look at the diamond matrix in a meteorite that landed in Sudan in 2008. This is considered the first evidence of a proto-planet that has helped form the terrestrial planets in our solar system.

2004 EW95 is the first carbon-rich asteroid confirmed to exist in the Kuiper belt and a relic of the primordial solar system. This curious object was probably formed in the asteroid belt between Mars and Jupiter before being launched billions of kilometers to its current location in the Kuiper belt.

The NASA / ESA Hubble Space Telescope celebrates its 28th anniversary in space with this wonderful and colorful image of the Lagoon Nebula 4,000 light years from Earth. While the entire nebula is 55 light years, this image only reveals a portion of about four light years.

This is a more stellar view of the Laguna Nebula, using Hubble's infrared capabilities. The reason why you can see more stars is because infrared is able to cut clouds of dust and gas to reveal the abundance of both young stars inside the nebula, as well as the farthest stars on background.

The Rosetta Nebula is 5,000 light years from Earth. The distinctive nebula, which some believe is more like a skull, has a hole in the middle that creates the illusion of its rose-like shape.

KIC 8462852, also known as Star of Boyajian or Star of Tabby, is 1,000 light years from us. It is 50% larger than our sun and 1000 degrees warmer. And it does not behave like any other star, obscuring itself and lighting up sporadically. The dust around the star, depicted here in an artist's illustration, may be the most probable cause of his strange behavior.

This inner slope of a Martian crater has several dark seasonal stripes called the "recurrent slope line" or RSL, which a November 2017 report interprets as granular flows rather than darkening due to the flow of water. The image comes from the HiRISE camera on Mars Reconnaissance Orbiter from NASA.

The impression of this artist shows a supernova explosion, which contains the brightness of 100 million suns. The Supernova iPTF14hls, which has exploded many times, may be the most massive and longest ever observed.

This illustration shows compounds of hydrocarbons that are divided into carbon and hydrogen inside ice giants, such as Neptune, turning into a "diamond rain".

This striking image is the stellar nursery in the Orion Nebula, where the stars are born. The red filament is a strip of 50-light-years-long ammonia molecules. Blue represents the gas of the Orion Nebula. This image is a collection of observations by Robert C. Byrd's Green Bank Telescope and NASA's wide-field infrared telescope. Explore the telescope. "We still do not understand in detail how the big clouds of gas in our galaxy collapse to form new stars," said Rachel Friesen, one of the co-principal investigators of the collaboration. "But ammonia is an excellent tracer of dense and stellar gas."

Here is how the Earth and its moon appear from Mars. The image is a composite of the best image of the Earth and the best image of the moon taken on November 20, 2016 by the Mars Reconnaissance Orbiter of NASA. The camera of the orbiter takes pictures in three bands of wave length: infrared, red and blue-green. Mars was about 127 million miles from Earth when the images were taken.

Initially it was thought that PGC 1000714 was a common elliptical galaxy, but a closer analysis revealed the incredibly rare discovery of a Hoag galaxy. It has a round core surrounded by two detached rings.

The NASA Cassini spacecraft took these images of the mysterious hexagonal jetstream of the planet in December 2016. The hexagon was discovered in images taken by the Voyager spacecraft in the early 80s. It is estimated that it has a diameter wider than two Earths.

A dead star emits a greenish glow in this image of the Hubble Space Telescope of the Crab Nebula, located about 6,500 light years from Earth in the constellation of Taurus. NASA has published the image for Halloween 2016 and presented the theme in its press release. The agency said that "the object from the monstrous aspect still has a wrist". At the center of the Crab Nebula is the crushed core, or "heart" of an exploded star. The heart turns 30 times per second and produces a magnetic field that generates 1 trillion volt, NASA said.

Peering through the thick dust clouds of the galactic swell, an international team of astronomers revealed the unusual mix of stars in the stellar cluster known as Terzan 5. The new results indicate that Terzan 5 is one of the primordial bricks of swelling, most likely the relic of the very first days of the Milky Way.

The conception of an artist by Planet Nine, who would be the farthest planet within our solar system. Similar cluster orbits of extreme objects on the edge of our solar system suggest that a huge planet is there.

An illustration of the orbits of the new objects of the Solar System, previously known and far away. The grouping of most of their orbits indicates that they will probably be influenced by something massive and far away, the proposed Planet X.

Greets the dark galaxy Libellula 44. Like our Milky Way, it has a halo of spherical clusters of stars around its nucleus.

A classical nova occurs when a white dwarf star gains material from its secondary star (a red dwarf) over a period of time, causing a thermonuclear reaction on the surface that eventually explodes into a single visible explosion. This creates a brightness increase of 10,000 times, depicted here in an artist's rendering.

Gravitational lenses and spatial deformation are visible in this image of near and distant galaxies captured by Hubble.

At the center of our galaxy, the Milky Way, researchers discovered an X-shaped structure inside a tightly packed group of stars.

Meet UGC 1382: What astronomers thought was a normal elliptical galaxy (left) was actually revealed to be a galaxy of gigantic disks made up of different parts when observed with ultraviolet and deep optical data (center and right). In a complete inversion of the normal structure of the galaxy, the center is younger than its outer spiral disk.

The NASA Hubble Space Telescope captured this image of the Crab Nebula and its "beating heart", which is a neutron star to the right of the two bright stars at the center of this image. The neutron star pulses 30 times per second. The colors of the rainbow are visible due to the movement of the materials in the nebula that occur during the time-lapse of the image.

The Hubble Space Telescope captured the image of a hidden galaxy that is weaker than Andromeda or the Milky Way. This shallow-surface galaxy, called UGC 477, is over 110 million light years away in the constellation of Pisces.

On April 19, NASA released new images of brilliant craters on Ceres. This photo shows the Haulani crater, which shows traces of landslides from the edge. Scientists believe that some craters on the dwarf planet are bright because they are relatively new.

This illustration shows millions of specks of dust that NASA's Cassini probe sampled near Saturn. Few dozens seem to come from beyond our solar system.

This image from the VLT Survey Telescope at the Paranal Observatory of ESO in Chile shows an extraordinary concentration of galaxies known as the Fornax cluster, located in the southern Hemisphere. In the middle of this cluster, in the middle of the three bright spots on the left side of the image, lies a galaxy cD – a galactic cannibal that has grown in size, consuming smaller galaxies.

This image shows the central region of the Tarantula Nebula in the Great Magellanic Cloud. The cluster of young and dense R136 stars, which contains hundreds of massive stars, can be seen in the lower right-hand corner of the Hubble Space Telescope.

Astronomers have discovered powerful aurora on a brown dwarf 20 light-years away. This is a concept of the artist of the phenomenon.

Venus, the bottom and Jupiter shine brilliantly over Matthews, North Carolina, Monday, June 29th. The apparent close encounter, called conjunction, gave a dazzling show in the summer sky. Although the two planets seem to be close, they are actually millions of miles away.

The frozen moon of Jupiter Europe could be the best place in the solar system to look for extraterrestrial life, according to NASA. The moon has roughly the size of the earth's moon, and there is evidence that it has an ocean under its icy crust that can hold twice as much water as the Earth. The 2016 NASA budget includes a $ 30 million request to plan a mission to investigate Europe. The image above was taken from the Galileo spacecraft on November 25, 1999. It is a 12-frame mosaic and is considered the best image of the side of Europe facing Jupiter.

This nebula, or cloud of gas and dust, is called RCW 34 or Gum 19. The brightest areas you can see are those where the gas is heated by young stars. Eventually the gas exploded like champagne after a bottle was uncorked. Scientists call this flow of champagne. This new image of the nebula was captured by the Very Large Telescope of the European Space Organization in Chile. RCW 34 is located in the constellation of Vela in the southern sky. The name means "sails of a ship" in Latin.

The Hubble Space Telescope captured images of the three great moons of Jupiter – Io, Callisto and Europa – passing by once.

Using powerful optics, astronomers found a planet-like body, J1407b, with rings 200 times larger than Saturn. This is the representation of an artist of the rings of the planet J1407b, which are eclipsing a star.

A portion of stars seems to be missing in this image from the La Silla Observatory in Chile. But the stars are still there behind a cloud of gas and dust called Lynds Dark Nebula 483. The cloud is about 700 light years old from the Earth in the constellation Serpens (The Serpent).

This is the largest image of the Hubble Space Telescope ever assembled. It is a part of the galaxy next door, Andromeda (M31).

NASA has captured an extraordinary new image of the so-called "Pillars of Creation", one of the most iconic discoveries of the space agency. The giant columns of cold gas, in a small region of the Eagle Nebula, were popularized by a similar image taken by the Hubble Space Telescope in 1995.

Astronomers using Hubble Space put this together image showing a small section of space in the constellation of the southern Fornax hemisphere. Inside this image of deep space there are 10,000 galaxies, which date back to a few hundred million years after the Big Bang.

Planetary Nebula Abell 33 looks similar to a ring in this image, taken using the Very Large European Southern Observatory Telescope. The blue bubble was created when an aging star loses its outer layers and a star in the foreground aligned with it to create a "diamond engagement ring" effect.

This image of Hubble looks like a floating marble or perhaps a giant, disembodied eye. But it is actually a nebula with a giant star in the middle. Scientists think that the star was 20 times more massive than our sun, but it is dying and is destined to become supernova.
