This one is Extra Strange. It's Also a Pulsar. Some of the most stunningly powerful objects in the sky aren't necessarily the prettiest to look at.
Magnetars are a rare type of rotating neutron star with some of the most powerful magnetic fields in the Universe. Astronomers have detected only thirty of these objects in and around the Milky Way—most of them detected by X-ray telescopes following a high-energy outburst.
Magnetars are an extremely rare and exotic breed of star. Of the hundreds of billions of stars in our Milky Way, there are fewer than 25 known magnetars.
It wasn't until 2008 that astronomers identified a neutron star that acted like a pulsar and emitted magnetically-powered bursts. This event confirmed magnetars to be a rare type of neutron star. There are only 31 confirmed magnetars in total (as of March 2020), out of around 3,000 known neutron stars.
Rarely, magnetars produce enormous eruptions called giant flares that produce gamma rays, the highest-energy form of light. Most of the 29 magnetars now cataloged in our Milky Way galaxy exhibit occasional X-ray activity, but only two have produced giant flares.
The "magnetar," or magnetic neutron star known as Soft Gamma Repeater 1806-20, is the most powerful known magnetic object in the universe. Only 10 of these unusual objects have been discovered.
The nearest known magnetar to Earth is 1E 1048.1-5937, located 9,000 light-years away in the constellation Carina.
Although magnetars are incredibly powerful, they would lose the battle with a black hole. Depending on the trajectory of the magnetar, as well as the size and mass of both the magnetar and the black hole, the magnetic monster would be eaten up either whole, or slowly, piece by piece.
0-1607, was first detected in March by NASA's Neil Gehreis Swift Telescope. It was first classified simply as a magnetar – one of only 31 ever found. Magnetars are a type of neutron star that has the strongest magnetic field ever detected – millions of billions of times stronger than that of Earth.
A cousin to the neutron star, magnetars have such huge magnetic fields that if you were unlucky enough to be within 1,000 miles (1600 km) from one, the magnetic force would rip iron apart from your bloodstream atom by atom, its gravity would rip you apart too probably.
Difference between Quasar , Pulsar and Magnetar
A Quasar can be light years in diameter whereas a Pulsar might only be as small as Manhatten Island in New York. A Magnetar is roughly about or larger than a Pulsar. A Quasar is at the centre of a galaxy, they are billions of light years away and very young.
With magnetars, the beams are believed to be powered by extremely strong magnetic fields, whereas in canonical pulsars they are powered by the rapid rotation of the star.
They are formed by the collapse of a star with a mass 10–25 times that of the Sun. The density of the interior of a magnetar is such that a tablespoon of its substance would have a mass of over 100 million tons.
Another type of neutron star is called a magnetar. In a typical neutron star, the magnetic field is trillions of times that of the Earth's magnetic field; however, in a magnetar, the magnetic field is another 1000 times stronger.
Astronomers may have discovered two of the strangest objects in the universe--two stars that appear to be composed of a dense soup of subatomic particles called quarks.
"[But] the magnetism of the magnetar will be stronger, in general." Luckily, we'll never have to worry about encountering a black hole or a magnetar close to Earth, but both could theoretically impact us here on Earth.
Definition of starquake
: a hypothetical violent shiver in the crust of a neutron star.
So if a white hole and black hole collided, we'd have a massive black hole roaming around the Universe, destroying everything in its path.
It is possible for two black holes to collide. Once they come so close that they cannot escape each other's gravity, they will merge to become one bigger black hole. Such an event would be extremely violent. Even when simulating this event on powerful computers, we cannot fully understand it.
That's about the same amount of energy in 10 trillion trillion billion megaton bombs! These explosions generate beams of high-energy radiation, called gamma-ray bursts (GRBs), which are considered by astronomers to be the most powerful thing in the universe.
Black holes are among the most destructive objects in the universe. Anything that gets too close to a black hole, be it an asteroid, planet, or star, risks being torn apart by its extreme gravitational field. By some accounts, the universe may eventually consist entirely of black holes.
They are 1⁄10 to 1⁄100 the brightness of a typical supernova, the self-detonation of a massive star.
The strongest magnetic field has a light pink color.
A gamma ray burst, the most powerful explosion known in the Universe, may have hit the Earth in the 8th Century. In 2012 researchers found evidence that our planet had been struck by a blast of radiation during the Middle Ages, but there was debate over what kind of cosmic event could have caused this.
