Hubble captures massive galaxy 400 mln light-years away

March 4, 2017

Washington, Mar 4: The Hubble space telescope has captured a new image showcasing an incredibly massive galaxy located under 400 million light-years away from the Earth.

hubbleThe galaxy UGC 12591 sits somewhere between a lenticular and a spiral, according to NASA. It lies in the westernmost region of the Pisces–Perseus Supercluster, a long chain of galaxy clusters that stretches out for hundreds of light-years - one of the largest known structures in the cosmos.

UGC 12591 itself is also extraordinary: it is incredibly massive, NASA said. The galaxy and its halo together contain several hundred billion times the mass of the Sun; four times the mass of the Milky Way.

It also whirls round extremely quickly, rotating at speeds of up to 1.8 million kilometres per hour. Observations with Hubble are helping astronomers to understand the mass of UGC 12591, and to determine whether the galaxy simply formed and grew slowly over time, or whether it might have grown unusually massive by colliding and merging with another large galaxy at some point in its past.

With the scrapping of Mitron and Remove China Apps from its Play Store gaining a lot of attention in India, Google on Thursday said that it removed a video app "for a number of technical policy violations", while adding that it also does not allow an app that "encourages or incentivizes users into removing or disabling third-party apps".

Both the apps became immensely popular in India within a short span of time due to the prevailing anti-China sentiment amid border tensions between India and China in Ladakh and calls by Indian activists to boycott Chinese products.

Reports suggested that the Mitron app is a repackaged version of TicTic, which is a TikTok clone.

The Remove China Apps was designed to help users identify applications of Chinese origin.

Without naming the apps, Google hinted that the Mitron app may make a comeback on the Play Store once it fixes some technical issues, but the chances of the Remove China Apps are thin.

"We have an established process of working with developers to help them fix issues and resubmit their apps. We've given this developer (of the video app) some guidance and once they've addressed the issue the app can go back up on Play," Sameer Samat, Vice President, Android and Google Play, said in a statement.

Google said that its Android app store was designed to provide a safe and secure experience for the consumers while also giving developers the platform and tools they need to build sustainable businesses.

Samat said that Google Play recently suspended a number of apps for violating the policy that it does not allow an app that "encourages or incentivizes users into removing or disabling third-party apps or modifying device settings or features unless it is part of a verifiable security service".

"This is a longstanding rule designed to ensure a healthy, competitive environment where developers can succeed based upon design and innovation. When apps are allowed to specifically target other apps, it can lead to behaviour that we believe is not in the best interest of our community of developers and consumers," Samat said.

"We've enforced this policy against other apps in many countries consistently in the past - just as we did here," he added.

The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.

Citing the current dismal aviation scenario, Air India is terminating the services of trainee cabin crew and cabin crew by withdrawing the offer of employment of those who were under training.

As per sources, the new crew and trainee pilots might reduce contracts from five years to one year. Sources said Air India is terminating 1,200 crew and employees who are more than 55-yr-old including 190 trainee pilots.

In a letter reviewed by IANS, Air India has informed an applicant who had been selected as cabin crew in August 2019 subject to successful completion of training.

"On behalf of Air India we would like to thank you for the interest shown by you in joining our organization. However, in view of the current aviation scenario, it would not be possible for Air India to impart any further training to you for engaging your services," the company said.

"In view of the above reasons, which are beyond the control of the company, it has been decided to discontinue your training arrangements and dispense with the offer of engagement with immediate effect. The bank guarantee furnished by you at the time of joining is returned herewith," Air India told the cabin crew.

"Once again on behalf of Air India we thank you for your cooperation and trust that you will appreciate the circumstances under which we are constrained to discontinue the training arrangements," the carrier said.
