Scientists Discover a New Gamma-ray Emitting Galaxy
The scientists from Aryabhatta Research Institute have discovered a new galaxy that emits gamma rays. The galaxy has been categorised as Narrow Line Seyfert 1 (NLS1). However, it is unique and different from the other NLS1s discovered so far.
It is 31 billion light years away from the earth. The galaxy is located at a high redshift.
The galaxy was discovered when scientists tried to trace red shifted galaxies. The redshifted galaxies are those galaxies that emit longer wavelength. As the wavelength of light gets longer the light turns redder. This is termed as "redshifted" in astronomy.
The NLS1s discovered so far that emitted gamma rays were at lower redshifts. This is the first gamma emitting NLS1 discovered to be at higher redshift.
The newly discovered gamma ray emitting NLS1 is 13.8 billion years old. It was formed when the universe was 4.7 billion years old.
Piyush Goyal Launches e-Santa
Commerce and Industry Minister Piyush Goyal said that e-Santa, an e-marketplace to connect aqua farmers and the buyers, will enable farmers to get a better price and the exporters to directly purchase quality products from them.
Launching e-Santa or Electronic Solution for Augmenting NaCSA farmers' Trade in Aquaculture, the minister said that the platform will change the traditional way of carrying out business on word-of-mouth basis and will make the system more formal and legally binding.
National Centre for Sustainable Aquaculture (NaCSA) is an extension arm of Marine Products Export Development Authority (MPEDA), under the department of commerce.
The farmers can sell their produce with a click of a button on e-Santa. It will provide more freedom, options and opportunities to the farmers. It will ensure fair prices for farmers & traceability.

Every Year 5,200 Tonnes of Extraterrestrial Dust Fall on Earth
Every year, 5,200 tonnes of extraterrestrial dust fall on Earth.
This gentle rain of bits of comets and asteroids far outweighs larger meteorites that hit the planet. Only about 10 tonnes of larger space rocks land on Earth annually.
Despite the large quantities, it's hard to detect space dust or track its annual accumulation in most places due to precipitation that washes dust away. And in most places, dust originating on Earth swamps dust from space.
But in Adélie Land, Antarctica, near the French-Italian Concordia research station, snowfall is very predictable and there is very little terrestrial dust. Over 20 years, French National Centre for Scientific Research (CNRS) physicist Jean Duprat and his colleagues have made six expeditions to the area to collect particles. The layers of space dust are well enough preserved in the region for researchers to estimate how much fell year after year.

UAE Names its First Female Astronaut Noura Al-Matroushi
The United Arab Emirates (UAE) revealed its next two astronauts, which includes the Kingdom's first-ever woman astronaut, that it plans to send for the future manned space missions at a state program. Noura al-Matroushi, the UAE's first female astronaut, and her counterpart Mohammed al-Mulla were identified by the ruler of Dubai, also the Prime Minister and vice president Sheikh Mohammed bin Rashid Al Maktoum.
The two astronauts, selected from among 4000 applicants across seven sheikhdoms, will commence training at NASA's Johnson Space Center in Houston, Texas, US.

Astronomers Discover Three New Galaxy Clusters
Dr. McDonald's team identified 11 cluster candidates around X-ray, radio, and mid-IR-bright sources, including six well-known clusters, two false associations of foreground and background clusters, and three new candidates: CHIPS 1356-3421, CHIPS 1911+4455 and CHIPS2155-3727.
With additional follow-up data from NASA's Chandra X-ray telescope, they confirmed two candidates: CHIPS 1356-3421 and CHIPS 1911+4455.
CHIPS 1911+4455 is similar in many ways to the rapidly-star-forming Phoenix cluster, but with a highly disturbed X-ray morphology on large scales.
This cluster invites further study, however, as it has a twisted shape with two extended arms, whereas all other rapidly-cooling clusters are circular.
WhatsApp Roles out New Features for Entrepreneurs
WhatsApp announced two new features to make it easier for people to know what's available and for entrepreneurs to quickly sell their products on WhatsApp for Business.
The company said that it is now providing businesses the ability to create and manage their catalog from WhatsApp web/desktop rather than just mobile phones.
Since many businesses manage their inventory from a computer, this new option will make it quick and easy to add new items or services so their customers know what's available.

Biden, Congress Roll Out Plans to expand National Science Foundation
The idea of massively expanding the budget and mission of the National Science Foundation (NSF) to help the United States out-innovate China is gaining political momentum in Washington, D.C.
In Congress, Senate Majority Leader Chuck Schumer (D–NY) is preparing to introduce a revised version of bipartisan legislation that would create a technology directorate at NSF and boost its funding by $100 billion. The changes address fears voiced by academic leaders that the new unit might disrupt the agency's culture and dilute NSF's ability to support basic research at universities.
In March, President Joe Biden lined up behind the concept, including both the new directorate and a $50 billion bump for NSF in his $2.3 trillion proposal to upgrade the nation's aging infrastructure. And late last month, Representative Eddie Bernice Johnson (D–TX), chair of the science committee of the U.S. House of Representatives, also backed both a new directorate and a larger NSF budget as part of a bill reauthorizing programs at the agency, which currently has an $8.5 billion budget.
