NASA Shares Pic Of Galaxy Trio Located 500 Million Light-Years From Earth

US space agency NASA (National Aeronautics and Space Administration) often delights space enthusiasts with updates on the latest discoveries related to galaxies, stars, and planets within our solar system. It also shares captivating images captured by its spacecraft. Now, in its most recent post, the space agency dropped a mesmerising photograph of an interacting galaxy pair known as Arp-Madore 2339-661. Located roughly 500 million light-years from Earth, the image was captured using NASA and the European Space Agency's Hubble Space Telescope. 

"A galactic tango! This striking #HubbleFriday image captures the gravitationally-interacting galaxy pair known as Arp-Madore 2339-661," NASA wrote in the caption. 

Take a look below: 

The two galaxies are in the process of merging, according to a statement from the European Space Agency. One galaxy is known as NGC 7733 - the smaller galaxy seen in the lower right - and the other is NGC 7734 - the larger galaxy in the upper left. However, hidden in the star-studded spiral arm of the smaller galaxy is yet another galaxy, referred to as NGC 7733N. 

"The third galaxy is currently referred to as NGC 7733N, and can actually be spotted in this picture if you look carefully at the upper arm of NGC 7733, where there is a visually notable knot-like structure, glowing with a different colour to the arm and obscured by dark dust," the ESA wrote in its blog.

"This could easily pass as part of NGC 7733, but analysis of the velocities (speed, but also considering direction) involved in the galaxy shows that this knot has a considerable additional redshift, meaning that it is very likely its own entity and not part of NGC 7733," it added.

Further, according to the European Space Agency, the three galaxies lie relatively close to each other in the constellation Tucana and are interacting gravitationally with one another. In fact, some science literature refers to them as a 'merging group,' which means they will ultimately become a single entity, ESA said. 

Meanwhile, since being posted, the picture has collected nearly 7 lakh likes on Instagram.

PM Modi To Reschedule 3-Nation Europe Visit As Tensions With Pakistan Soar

Prime Minister Narendra Modi has put his three-nation Europe visit on hold as tensions between India and Pakistan have surged in the wake of the terror attack in Jammu and Kashmir's Pahalgam in which 26 civilians were killed by Pak-linked terrorists in a religiously-motivated terror attack. India responded on Wednesday with precision missile strikes on terror camps in Pakistan and Pakistan-occupied Kashmir. PM Modi, who is closely-monitoring the situation, has reportedly asked for his visit to Croatia, Norway, and the Netherlands, which was due next week, to be rescheduled. As per his original schedule Prime Minister Modi was to commence his official visit to the three nations on May 13. He was also going to participate in the India-Nordic Summit in Oslo on May 15 and 16. All three countries have been informed about the change in PM Modi's schedule. They have also been appraised about the current situation between India and Pakistan. Last month too, on the day of the Pahalga...

After Nitish Kumar's 'Praise', BJP Says Doors Closed For Him

The opposition BJP in Bihar on Thursday said that its doors were "closed" for Chief Minister Nitish Kumar who dumped the saffron party a year ago, stripping it of power in the state. State BJP President Samrat Choudhary made the averment to this effect in reply to queries from journalists about the Janata Dal United leader's address to the convocation ceremony of Mahatma Gandhi Central University at Motihari. Speaking in the presence of President Droupadi Murmu and Governor Rajendra Arlekar, Mr Kumar had freely spoken of the tussle he had with the then Congress government at the Centre for getting a university approved for Motihari, where Mahatma Gandhi had launched the Champaran Satyagraha. Without mentioning Prime Minister Narendra Modi by name, Mr Kumar acknowledged that the project saw the light of the day only after a change of guard "in 2014" as the UPA government "initially refused and after much persuasion agreed in principle but did not move for...

Fifteen monitoring stations of the city recorded air quality levels in the 'severe' zone, having AQI readings over 400, data showed. The city also recorded its lowest nighttime temperature so far, as thick smog and haze shrouded it in a dense cover during the morning and evening hours. The minimum temperature recorded on Sunday was 16.5 degrees Celsius, 1.2 degrees above normal, according to the weather department. The national capital's 24-hour average Air Quality Index (AQI), recorded at 4 pm every day, stood at 382, worsening from 316 the previous day. The locations where air pollution levels reached the 'severe' zone are Anand Vihar, Ashok Vihar, Bawana, Dwarka, Jahangirpuri, Mundka, NSIT Dwarka, Najafgarh, Nehru Nagar, Okhla Phase 2, Patparganj, Punjabi Bagh, Rohini, Wazirpur and Vivek Vihar...
