NASA’s Hubble Telescope Captures Stunning Image Of ‘Lopsided’ Spiral Galaxy 120 Million Light-Years Away
Nasa’s 31-year-old Hubble Space Telescope has made another incredible discovery — it has found a “lopsided” spiral galaxy that has been deformed by the gravitational tug of another nearby galaxy. NASA has shared the stunning image of the galaxy called “NGC 2276”, which is located in the constellation Cepheus, about 120 million light-years away from the Earth. In the image, dust of blue stars surrounds the yellowish core just like the scene from the Avengers: Age Of Ultron movie when the AI Ultron attacks and tries to swallow another AI Jarvis developed by Tony Stark, aka Iron Man.
NASA said the spiral galaxy looks a bit lopsided because of 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 post on Instagram.
In a statement on its website, NASA said that a bright hub of older yellowish stars normally lies directly in 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,” said NASA. This gravitational pull between galaxies that pass close enough is not uncommon in the universe, but all such close encounters look differently.
Commenting on the image on Instagram, a user, Ilaibaah, wrote, “That’s the most gigantic tug of war I’ve seen.”
“Is that other galaxy the main cause of those blue stars,” asked a person with the username Geejay1976.
Another user, Astro.nor, said that the colour of a star was due to its temperature. “Blue stars are hotter, red stars are cooler (but still very, very hot),” the user added.
A spiral galaxy is a twisted collection of hot young stars and gas. Most of the galaxies that scientists have discovered, roughly 72 per cent of all the galaxies, are spiral, as opposed to elliptical and irregular galaxies. Our Milky Way is an example of a spiral galaxy.
Hubble Space Telescope
The Hubble Space Telescope is a project of international cooperation between the European Space Agency (ESA) and NASA. To celebrate the 31st anniversary of the Hubble Space Telescope in April this year, NASA had released a celebratory image of one of the brightest stars in our galaxy, named AG Carinae, located approximately 20,000 light-years away.
Since its launch in 1990, the Hubble Space Telescope has made more than 1.4 million observations as it has an “unobstructed view” of the universe, according to NASA.
NASA’s Orion Spacecraft Enters Lunar Orbit a Week After Artemis I Launch
NASA’s Orion spacecraft was placed in lunar orbit Friday, officials said, as the much-delayed Moon mission proceeded successfully.
A little over a week after the spacecraft blasted off from Florida bound for the Moon, flight controllers “successfully performed a burn to insert Orion into a distant retrograde orbit,” the US space agency said on its website.
The spacecraft is to take astronauts to the Moon in the coming years — the first to set foot on its surface since the last Apollo mission in 1972.
This first test flight, without a crew on board, aims to ensure that the vehicle is safe.
“The orbit is distant in that Orion will fly about 40,000 miles above the Moon,” NASA said.
While in lunar orbit, flight controllers will monitor key systems and perform checkouts while in the environment of deep space, the agency said.
It will take Orion about a week to complete half an orbit around the Moon. It will then exit the orbit for the return journey home, according to NASA.
On Saturday, the ship is expected to go up to 40,000 miles beyond the Moon, a record for a habitable capsule. The current record is held by the Apollo 13 spacecraft at 248,655 miles (400,171 km) from Earth.
It will then begin the journey back to Earth, with a landing in the Pacific Ocean scheduled for December 11, after just over 25 days of flight.
The success of this mission will determine the future of the Artemis 2 mission, which will take astronauts around the Moon without landing, then Artemis 3, which will finally mark the return of humans to the lunar surface.
Those missions are scheduled to take place in 2024 and 2025, respectively.
ISRO’s RH200 Sounding Rocket Registers 200th Consecutive Successful Launch
ISRO on Wednesday announced that RH200, the versatile sounding rocket of the Indian space agency, has registered its 200th consecutive successful launch from the shores of Thumba, Thiruvananthapuram. The Indian Space Research Organisation (ISRO) has termed it a “historic moment”. It was witnessed by former President Ram Nath Kovind and ISRO chairman S Somanath, among others.
The successful flight of RH200 took off from the Thumba Equatorial Rocket Launching Station (TERLS).
“Indian sounding rockets are used as privileged tools for the scientific community for carrying out experiments on meteorology, astronomy and similar branches of space physics,” an ISRO statement said.
Campaigns such as Equatorial ElectroJet (EEJ), Leonid Meteor Shower (LMS), Indian Middle Atmosphere Programme (IMAP), Monsoon Experiment (MONEX), Middle Atmosphere Dynamics (MIDAS), and Sooryagrahan-2010 have been conducted using the sounding rocket platform for scientific exploration of the Earth’s atmosphere, it said.
The Rohini Sounding Rocket (RSR) series have been the forerunners for ISRO’s heavier and more complex launch vehicles, with a continued usage even today for atmospheric and meteorological studies, the national space agency headquartered here said.
“The 200th consecutive successful flight stands testimony to the commitment of Indian rocket scientists towards unmatched reliability demonstrated over the years,” it said.
Meanwhile, ISRO is all set to launch PSLV-C54/ EOS-06 mission with Oceansat-3 and eight nano satellites, including one from Bhutan, from the Sriharikota spaceport on November 26. The launch is scheduled at 11.56am on Saturday, the national space agency said on Sunday.
Last week, ISRO announced that the payload capability of India’s heaviest LVM3 rocket has been enhanced by up to 450kg with a successful engine test. According to the Indian Space Research Organisation, the CE20 cryogenic engine indigenously developed for Launch Vehicle Mark 3 (LVM3) was subjected to a successful hot test at an uprated thrust level of 21.8 tonnes for the first time on November 9, according to the country’s national space agency.
PSLV to Launch Pixxel’s Hyperspectral Imaging Satellite Anand on November 26
Spacetech startup Pixxel is set to launch its third hyperspectral satellite – Anand – onboard ISRO’s Polar Satellite Launch Vehicle (PSLV) from the Sriharikota spaceport on Saturday.
Anand is a hyperspectral microsatellite weighing less than 15 kg but having more than 150 wavelengths that will enable it to capture images of the earth in greater detail than today’s non-hyperspectral satellites that have not more than 10 wavelengths.
The imagery from the satellite can be used to detect pest infestation, map forest fires, identify soil stress and oil slicks amongst other things, a statement from Pixxel said on Monday.
“After more than 18 months of delay, many many retests, and more than two years of sweat and hard work by the team, we are finally launching this week,” Awais Ahmed, Founder and CEO of Pixxel said on Twitter.
Pixxel’s hyperspectral satellites are unique in their ability to provide hundreds of bands of information with global coverage at a very high frequency, making them ideal for disaster relief, agricultural monitoring, energy monitoring and urban planning applications, the company said.
The satellites are equipped to beam down up to 50 times more information with unprecedented detail, compared with other conventional satellites in orbit.
Pixxel has already inked partnerships with Rio Tinto and Data Farming which will use hyperspectral datasets to identify mineral resources and monitoring active and determining crop issues respectively.
The imagery from this will provide the team targeted inputs to improve the form factor and imaging capabilities of the next batch of commercial-grade satellites.
With this launch, Pixxel moves closer to achieving its vision of building a health monitor for the planet through a constellation of cutting-edge hyperspectral small satellites in space.
Pixxel is backed by Lightspeed, Radical Ventures, Relativity’s Jordan Noone, Seraphim Capital, Ryan Johnson and Accenture among others.
