An interstellar meteor, the DNA of the Crusaders and water on the moon: this week in space and science


One of the brightest planetary nebulae in the sky and discovered for the first time in 1878, the nebula NGC 7027 can be seen to the constellation Cygnus.

The 6478 Gault asteroid is seen with NASA / ESA's Hubble Space Telescope, showing two narrow, comet-like debris tails, which indicate that the asteroid is in the process of self-destructing. The light trails surrounding the asteroid are stars in the background. The asteroid Gault is located 214 million kilometers from the Sun, between the orbits of Mars and Jupiter.

The ghostly shell of this image is a supernova and the bright path away from it is a pulsar.

Hidden in one of the darkest corners of the Orion constellation, this cosmic bat spreads its hazy wings through interstellar space two thousand light-years apart. It is illuminated by the young stars nestled in its core – although they are surrounded by opaque clouds of dust, their light rays still illuminate the nebula.

In this illustration, several rings of dust surround the sun. These rings are formed when the gravities of the planets bring back grains of dust in orbit around the sun. Recently, scientists have detected a ring of dust on the orbit of Mercury. Others have speculated that the Venus Dust Ring is a group of co-orbital asteroids never detected before.

The Hubble Space Telescope has discovered a dwarf galaxy hidden behind a large group of stars located in our cosmic neighborhood. It is so old and virgin that researchers have dubbed it a "living fossil" from the beginning of the universe.

How did massive black holes form in the primitive universe? The rotating gas disk of this halo of dark matter splits into three tufts that collapse under their own gravity to form supermassive stars. These stars will quickly collapse and form huge black holes.

NASA's Spitzer Space Telescope has captured this image of the Large Magellanic Cloud, a satellite galaxy connected to our own galaxy, the Milky Way. Astrophysicists now believe that this could collide with our galaxy in two billion years.

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

These three panels reveal a supernova before, during and after its event, 920 million light years from Earth (from left to right). The supernova, nicknamed iPTF14gqr, is unusual because, even though the star was massive, its explosion was fast and weak. Researchers believe this is due to a star that siphoned off its mass.

Here is an illustration of the artist illustrating what a Neptune-sized moon would look like in orbit around the giant gas-filled Kepler-1625b exoplanet in a star-shaped system 8,000 light-years from Earth. It could be the first exomoon ever discovered.

2004 EW95 is the first confirmed carbon rich asteroid in the Kuiper Belt and a relic of the primordial solar system. This curious object probably formed in the asteroid belt between Mars and Jupiter before being projected to billions of kilometers from its current home in the Kuiper Belt.

The NASA / ESA Hubble Space Telescope celebrates its 28th anniversary in space with this amazing and colorful image of the lagoon nebula at 4,000 light-years from Earth. Although the nebula has a total length of 55 light-years, this image only reveals one part about four light-years away.

Here's a more star-studded view of the lagoon nebula, using Hubble's infrared capabilities. The reason you can see more stars is because the infrared is able to cut through the clouds of dust and gas to reveal the abundance of two young stars in the nebula , as well as more distant stars in the background.

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

KIC 8462852, also known as the Boyajian Star or Tabby Star, is 1,000 light-years away from us. It's 50% bigger than our sun and 1,000 degrees warmer. And it does not behave like any other star, darkening and lightening sporadically. The dust around the star, shown here in the illustration of an artist, may be the most likely cause of his strange behavior.

This internal slope of a Martian crater presents several seasonal dark streaks called "Recurrent Slope Lines" (RSL), which a November 2017 report interprets as granular flows rather than darkening it due to of the flow of water. The image comes from the HiRISE camera of NASA's March reconnaissance orbiter.

The print of the artist shows a supernova explosion containing the brightness of 100 million suns. The Supernova iPTF14hls, which has exploded several times, could be the most massive and durable ever.

This striking image is the stellar nursery of the Orion Nebula, the birthplace of the stars. The red filament is a segment of ammonia molecules measuring 50 light-years in length. Blue represents the gas of the Orion nebula. This image is a composite of the Robert C. Byrd Green Bank telescope and NASA's Survey Infrared Survey telescope. "We still do not understand in detail how big gas clouds 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 gas forming stars."

This is what the Earth and its moon look like since March. The image is a composite of the best image of the Earth and the best moon image, taken on November 20, 2016 by NASA's Mars Orbiter Recognition. The camera of the orbiter takes pictures in three bands of wave length: infrared, red and blue-green. Mars was about 127 million kilometers from Earth when the images were taken.

It was initially thought that PGC 1000714 was a common elliptical galaxy, but further analysis revealed the incredibly rare discovery of a Hoag type galaxy. It has a round nucleus surrounded by two detached rings.

NASA's Cassini spacecraft took these images of the mysterious jetstream of the hexagon-shaped planet in December 2016. The hexagon was discovered on images taken by the Voyager spacecraft in the early 1980s. It is estimated that it has a diameter wider than two lands.

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 Taurus. NASA released the image for Halloween 2016 and picked up the theme in its press release. The agency said that "the object in the macabre appearance always has a pulse". In the center of the Crab Nebula is the crushed kernel, or "heart" of an exploded star. The heart rotates 30 times per second and produces a magnetic field that generates 1,000 billion volts, NASA said.

Looking through the thick clouds of galactic bulb dust, an international team of astronomers revealed the unusual mixture of stars in the group of stars known as Terzan 5. new findings indicate that Terzan 5 is one of the prime building blocks of the relic of the very first days of the Milky Way.

Say hello to the dark dragonfly galaxy 44. Like our milky way, it is surrounded by a halo of spherical clusters.

A classic nova occurs when a white dwarf star gains matter from its secondary star (a red dwarf) during a given period, causing a thermonuclear reaction to the surface that eventually fires in a single explosion visible. This creates a brightness 10,000 times greater, described here in the rendering of an artist.

Meet UGC 1382: What astronomers thought to be a normal elliptical galaxy (left) was actually revealed to be a massive disk galaxy composed of different view parts with deep optical and ultraviolet optical data (center and right). In a complete reversal of the normal structure of the galaxy, the center is younger than its outer spiral disk.

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

Venus, Low, and Jupiter brilliantly shine above Matthews, NC on Monday, June 29. The apparent close encounter, called conjunction, gave a dazzling spectacle in the summer sky. Although the two planets seem to be close to each other, they are actually millions of miles away.

The frozen moon of Jupiter, Europa, could be the best place in the solar system to search for extraterrestrial life, according to NASA. The moon is about the size of the moon and there is evidence that there is an ocean under its frozen crust that can hold twice as much water as the Earth. NASA's 2016 budget includes a request for $ 30 million for planning a fact-finding mission on Europa. The above image was taken by Galileo Probe on November 25, 1999. It is a mosaic of 12 images that is considered the best image of the Europe side that faces Jupiter.

This nebula, or cloud of gas and dust, is called RCW 34 or Gum 19. The brightest areas you can see are where the gas is heated by young stars. Finally, the gas explodes like champagne after uncorking a bottle. Scientists call this the 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 in the Vela constellation in the southern sky. The name means "sailing sails" in Latin.

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