Nasa’s 31-year-old Hubble Space Telescope has made one other unimaginable discovery — it has discovered a “lopsided” spiral galaxy that has been deformed by the gravitational tug of one other close by galaxy. NASA has shared the beautiful picture of the galaxy referred to as “NGC 2276”, which is situated within the constellation Cepheus, about 120 million light-years away from the Earth. In the picture, mud of blue stars surrounds the yellowish core similar to the scene from the Avengers: Age Of Ultron film when the AI Ultron assaults and tries to swallow one other AI Jarvis developed by Tony Stark, aka Iron Man.
NASA mentioned the spiral galaxy appears to be like a bit lopsided due to the “galactic game of tug-of-war”. “A neighbouring galaxy is gravitationally tugging on its disk of blue stars, pulling the stars on one side of the galaxy outward,” NASA captioned the submit on Instagram.
In a assertion on its web site, NASA mentioned that a brilliant hub of older yellowish stars usually lies immediately within the centre of most spiral galaxies, and added “but the bulge in NGC 2276 looks offset to the upper left”.
“In reality, a neighbouring galaxy to the right of NGC 2276 (NGC 2300, not seen in the image) is gravitationally tugging on its disk of blue stars, pulling the stars on one side of the galaxy outward to distort the galaxy’s normal fried-egg appearance,” mentioned NASA. This gravitational pull between galaxies that cross shut sufficient will not be unusual within the universe, however all such shut encounters look in another way.
Commenting on the picture on Instagram, a consumer, Ilaibaah, wrote, “That’s the most gigantic tug of war I’ve seen.”
“Is that other galaxy the main cause of those blue stars,” requested a particular person with the username Geejay1976.
Another consumer, Astro.nor, mentioned that the color of a star was resulting from its temperature. “Blue stars are hotter, red stars are cooler (but still very, very hot),” the consumer added.
Spiral galaxy
A spiral galaxy is a twisted assortment of sizzling younger stars and fuel. Most of the galaxies that scientists have found, roughly 72 per cent of all of the galaxies, are spiral, versus elliptical and irregular galaxies. Our Milky Way is an instance of a spiral galaxy.
Hubble Space Telescope
The Hubble Space Telescope is a undertaking of worldwide cooperation between the European Space Agency (ESA) and NASA. To have a good time the thirty first anniversary of the Hubble Space Telescope in April this yr, NASA had launched a celebratory picture of one of many brightest stars in our galaxy, named AG Carinae, situated roughly 20,000 light-years away.
Since its launch in 1990, the Hubble Space Telescope has made greater than 1.4 million observations because it has an “unobstructed view” of the universe, in response to NASA.
