New research suggests that the collision of space objects that created Earth’s moon may have robbed it of 10% to 60% of its original atmosphere.

Most scientists believe that about 4 billion years ago when Earth was still developing, a massive object the size of Mars hit the planet, sending vaporized particles from the collision into space, which were then bound together through gravity to form Earth’s moon.

The so-called “impact hypothesis” is one of three key theories of the moon’s formation. The others suggest the moon was either formed at the same time as Earth, or that it was captured by Earth’s gravitational field as it traveled through space. In the new study published Wednesday in the Astrophysical Journal Letters, researchers focused on the impact theory, and ran more than 300 computer simulations of massive object collisions with rocky planets with thin atmospheres like Earth.

The scientists factored in the angle at which the objects hit the planet, the speed of the impact, as well as the size and mass of the colliding object.

Previous research suggested impact collisions during the late stages of a planet’s formation period can affect its atmosphere. Expanding on this idea, the simulations in this study revealed that a collision like the one that could have created the moon would have cost the Earth a significant portion of its atmosphere.

Lead researcher on the study, Durham University cosmologist Jacob Kegerreis, said that while the computer simulations do not directly explain how the moon was created,

“the effects on the Earth’s atmosphere could be used to narrow down the different ways it might have been formed.”

Kegerreis said the study also shows a new way to study how similar collisions lead to loss of atmosphere on young, rocky planets. Or, he said, the study also suggests such collisions could lead to significant atmospheric gains if the colliding object also has a thick atmosphere. (VOA)

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday

The Centre will launch a pilot project on the use of indigenously manufactured drones for delivering medicines in the undulating landscape of Jammu and surrounding areas from Saturday with a focus on vaccines delivery initially. "This is going to be a pilot project for the area. The drone is developed and manufactured entirely by our scientists," Union Minister for Science & Technology, Dr Jitendra Singh told mediapersons. Singh said he himself will be launching the project at Jammu.

The drone is developed by the scientists at Bengaluru's National Aerospace Laboratories (NAL), a constituent of Council of Scientific and Industrial Research (CSIR), an autonomous Society that is headed by the Prime Minister. For now, the delivery would be limited to Covid vaccines and once successful, it would be expanded to be used for regular delivery of medicines in the remote, hilly areas.

According to him Amitabh Bachchan is a great actor in the industry.

Bollywood actor Abhishek Bachchan shares how he feels when people compare him with his father Amitabh Bachchan on the singing reality show 'Sa Re Ga Ma Pa'. He also requests contestant Rajshree Bag to sing a track 'Bahon Mein Chale Aao' featuring his mother Jaya Bachchan.

Abhishek said after looking at the performance of Rajshree, who is often compared with Lata Mangeshkar on the show, that she reminds him of being compared with his father. "Rajshree, whenever I have got the chance to watch the show, I've seen people compare you to Lata didi. It actually reminded me about how people compare me with my father and ask me how I feel about it."

According to him Amitabh Bachchan is a great actor in the industry and this is what he says to everyone making these comparisons. "My answer to them is that there's no greater actor in this film industry than Amitabh Bachchan and if I'm being compared to him, I am sure I must have done something good."

"Similarly, your voice has a different kind of magic like Lata ji and that's why people are comparing your voice with her. I feel you should always take this as a compliment," he concluded. 'Sa Re Ga Ma Pa' airs on Saturday and Sunday on Zee TV. (IANS/ MBI)

Winters in India have always beckoned for that hot, steaming bowl of tomato and pepper rasam or the mellow, millet based Raab. Certain dishes like sarson ka saag, undhiyu, nimona pulao are winter specialites in the country. Seasonal food has always been an Indian speciality -- we switch our choice in fruits, vegetables, sometimes even grains with the onset of different season. The preference of using specific ingredients during certain climates is visible in our sweets as well. It's common to find local and traditional delicacies made of jaggery, instead of sugar during the winters. Case in point -- the Nolen Gur Rasgulla, a speciality made in Odisha and West Bengal between November to February.
