Chandrayaan-2 Orbiter Makes First-of-Its-Kind Observations on Global Distribution of Argon-40 in the Moon’s Exosphere

ISRO’s Chandrayaan-2 orbiter has detected Argon in the equatorial and mid-latitude regions of the Moon. Argon is an inert, colourless and odourless noble gas. It serves as important tracer to study the processes of surface-exosphere interaction. The ‘exosphere’ is the outermost region of the upper atmosphere of a celestial body.

Argon-40 has been detected for the first time by Indian Space Research Organisation (ISRO) using data from the CHACE-2 and LADEE missions. The vast majority of Argon occurs in its isotopic form of Argon-40, resulting from the radioactive disintegration of Potassium-40 (K-40) present below the lunar surface. It diffuses through the inter-granular space and makes its way up to the lunar exosphere through seepages and faults.

Chandrayaan-2’s findings of Ar-40 up to the mid-latitude regions play a significant role in bridging the gap in the knowledge of the element’s presence on the Moon, according to researchers at the University of Bristol. The observations suggest there is a need for improvement in our understanding of the surface-exosphere interactions and source distributions of Ar 40, they say.

Husband Mark Zuckerberg fulfils ‘disco queen’ Priscilla Chan’s demand for a party and how

Mark Zuckerberg’s party for Priscilla Chan has won people over. Many were surprised by the tech billionaire’s makeover.

Mark Zuckerberg never shies away from sharing glimpses of his sweet and heartwarming moments with his family. From sharing pics of a statue of his wife, Priscilla Chan, to turning into a nail artist for his daughter, he regularly posts visuals which wow people. In a similar post, he shared pictures to show what he did when his “disco queen” wife asked for a party.

“Disco queen wanted a party,” Zuckerberg wrote as he posted the pictures. The first photo shows the couple sharing an intimate moment while kissing each other. The other images show them enjoying the party, with both dressed in shimmery clothes.

What did social media say?

“I always knew you were this cool,” posted an Instagram user. “He changed after attending Ambani’s wedding,” joked another. This has been a viral remark after Mark Zuckerberg’s recent wardrobe update, including Hawaiian shirts and a thick gold chain, which coincidentally happened after he attended Anant Ambani and Radhika Merchant’s first pre-wedding festivities.

“Absolutely enjoying this beautiful life,” commented another. A third expressed, “Zuck’s glow up needs to be studied in universities.” A fourth shared, “Couple goals!”

A fifth wrote, “Priscilla is on fire! And you too.” Many reacted to the post using heart or fire emoticons.

Roman-inspired statue

A few days ago, the Meta CEO unveiled a giant statue in his backyard. Created by Daniel Arsham, it is a larger-than-life statue of his wife.

He met Priscilla Chan at Harvard University in 2003 as a student. The couple later got married in 2012. They have three daughters: Maxima, August (born August 2017), and Aurelia.
