The Chandra’s Atmospheric Composition Explorer-2 (CHACE-2) payload aboard the Chandrayaan-2 Orbiter has detected Argon-40, said Indian Space Research Organisation (ISRO).

According to ISRO, the Orbiter that is orbiting the moon has detected Argon-40 from an altitude of about 100 km.


Argon-40 (40Ar), which is one of the isotopes of the noble gas Argon, is an important constituent of the lunar exosphere, ISRO said on Thursday.

Planetary scientists prefer to call the thin gaseous envelope around the Moon as the ‘Lunar exosphere’ since it is so tenuous that the gas atoms very rarely collide with each other, ISRO said.

According to ISRO, Argon-40 or 40Ar originates from the radioactive disintegration of Potassium-40 (40K).

The radioactive 40K nuclide, which is present deep below the lunar surface, disintegrates to 40Ar, which, in turn, diffuses through the intergranular space and makes way up to the lunar exosphere through seepages and faults.

The Indian space agency said CHACE-2 payload, is a neutral mass spectrometer-based payload which can detect constituents in the lunar neutral exosphere in the range of 1-300 amu (atomic mass unit).

As part of its early operation, it has detected 40Ar in the lunar exosphere from an altitude of about100 km, capturing the day-night variations of concentration.

The 40Ar being a condensable gas at the temperatures and pressures that prevail on the lunar surface, condenses during lunar night. After lunar dawn, the 40Ar starts getting released to the lunar exosphere, ISRO said. (IANS)

Diwali is known for gifting and jewellery tops the list, with the focus on buying gold and diamonds.

Diwali is known for gifting and jewellery tops the list, with the focus on buying gold and diamonds. ORRA jewellery, a trusted diamond jewellery brand is gearing up for the festive and bridal season. As they open their 50th store in the country, IANSlife caught up with Dipu Mehta, Managing Director, ORRA, to find out how the company plans to ramp up its now 50 company-owned and operated stores, expanding its retail presence in Tier-1 and 2 cities and target the millennial segment.

Read Excerpts:

Q: The brand is expanding in tier-2 and tier-3 cities, is brick and mortar the way forward to create a presence in this segment?

A: ORRA currently is expanding in metros plus tier-2 cities. But we aren't opening stores in any new markets. We are only opening in markets where we are already present. We are increasing the number of stores within cities as the demand for jewellery buying has also increased. Currently, we are present in 25 cities with 50 stores, and by the end of the month, we would be launching another seven stores.
Also with a category like jewellery, it is important to have brick and mortar stores as the customers like to see and hold higher value jewellery before purchasing. Jewellery buying is an important decision to the customers and having a store gives them that assurance.

The Centre on Wednesday directed all Union Ministries and Departments to clear Air India's dues immediately.

The Centre on Wednesday directed all Union Ministries and Departments to clear Air India's dues immediately. An office memorandum from the Finance Ministry's Department of Expenditure said: "Recently, the Government of India has decided to disinvest Air India, and the process of disinvestment of Air India and Air India Express is ongoing."

"Air India has stopped extending credit facilities on account of purchase of air tickets. Therefore, all Ministries or Departments are directed to clear Air India's dues immediately." "Air tickets from Air India may be purchased in cash till further instructions."



In 2009, the Centre had mandated that Central government officers travel via Air India for all official purposes including availing of LTC. On Monday, conglomerate Tata Group entered into a share purchase agreement with the Central government for buying out the latter's stake in national carrier Air India, Air India Express, and AISATS.

Sports betting has become increasingly popular among the youth in recent times

Sports betting has been around for centuries for the audience to not only watch the sport but to get more deeply involved in the match. It is a fun and often profitable activity for the viewer to win some extra fortune or simply get some extra sweat while watching the game. At first glance, sports betting may look like it's pure luck, but when you indulge deeper into the activity you realize it is more of a calculative and research activity than just pure luck. We must note that yes, luck does play a certain role to some extend but a win is not completely dependent on luck, if you're putting your bets on a certain team you have to make sure to do some research about the players on the team, history of wins and losses of the team and compare the probability of winning and then place bets.

Even though sports betting has existed since the ancient era, it was not until recently that it became increasingly popular among the youth. This happened due to the legalization of the activity and the rise of online sports betting. The technological revolution has expanded the sports betting industry, offering the bettors new markets and ways to bet. The only major difference between online bookmarkers and traditional brick-and-mortar venues of sports betting is that now you can place bets online from your mobile devices, laptops, computers etc.
