Map of 4.4 Million Galaxies

Using the Low-Frequency Array (LOFAR) radio, more than a quarter of the northern sky was mapped by astronomers from Durham University who collaborated with a team of international scientists for this project. This map provides an incredibly detailed radio image of over 4.4 million objects, as well as a very dynamic picture of our Universe.
The vast majority of these mapped objects are galaxies with huge black holes or rapidly growing young stars that are billions of light-years away.
Flaring stars within the Milky Way and colliding groups of faraway galaxies are among the rarer objects discovered.
This is by far the largest data release from the LOFAR Two-metre Sky Survey.
This data release includes nearly four million objects that at radio wavelengths are new discoveries and around a million objects that have never been seen before with any telescope.

China's Record Launch of 22 Satellites

China launched a Long March-8 rocket to place 22 satellites in space.
With the launch, China set a domestic record for the most spacecraft launched by a single rocket.
The rocket blasted off at the Wenchang Spacecraft Launch Site in southern Hainan Province. It sent the satellites into preset orbits.
It marked the 409th flight of Long March carrier rockets.
These satellites will be used for commercial remote sensing services, forest fire prevention, marine environment monitoring, and disaster mitigation.

Astronomers Identify Real-Life Planet with Two Suns - Like "Tatooine" From Star Wars

Astronomers used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker in "Star Wars."
The planet, Kepler-16b, is about 245 light years from Earth, is a gas giant, and is roughly the size of Saturn. Scientists already knew that the planet existed, but in a recent study, an international team of astronomers explained how they successfully applied a technique that hadn't been previously used to observe a planet orbiting two stars.
The technique, called the radial velocity method, has long been used in astronomy. (The first planet ever found around a sun-like star was found using radial velocity – and was found using the same telescope astronomers used to find this one.)

Biggest Bacterium ever Discovered Amazes Scientists with its Complexity

Scientists discovered an absolutely massive bacterium that can be seen without the aid of a microscope and lurks among the mangroves of Grande-Terre in the Caribbean.
The single-celled organism can grow up to 0.78 inches (2 centimeters) long and resembles a thin string. The bacterium carries all its DNA inside a membranous pouch, unlike most bacteria, whose genetic material floats, unbound, within their cells. This feature not only sets the newfound microbe apart from other bacteria, but also distinguishes it from other prokaryotes — a group of organisms with very small, simple cell structures. The group includes organisms found in the Bacteria and Archaea domains.

Dawn Detects Organics and Salts in Giant Crater on Ceres

Using the Framing Camera (FC) and the Visible and Infrared Spectrometer (VIR) aboard NASA's Dawn spacecraft, planetary researchers spotted bright brine residues and organics in the Urvara basin, one of the largest impact structures on the dwarf planet Ceres. The results strengthen the hypothesis that Ceres is and has been a geologically active world even in recent epochs, with salts and organic-rich material playing a major role in its evolution.
This dwarf planet is a survivor of the earliest period of Solar System formation and thus detailed knowledge about its interior provides fundamental insights into the formation and evolution of volatile-rich planetary embryos that originated within the protoplanetary disk.

Infosys Launches Metaverse Foundry

Bengaluru-based IT services major Infosys launched Metaverse Foundry that will help its clients with adaptation, creation and also help scale the new technology. The company has already developed 100 use cases and is actively working with clients on the same.
The move comes at a time when companies around the world are putting a huge focus on the metaverse. From Meta, formerly Facebook, and Microsoft, to IT services providers, the companies are investing significantly in the space.

Multi-terabit Undersea Cable to Connect Maldives with India and Singapore

Reliance Jio Infocomm Ltd. (Jio) will land the next generation multi-terabit undersea cable in Maldives to connect the south Asian country with India and Singapore. According to Jio, the new India-Asia-Xpress (IAX) undersea cable in Hulhumale, Maldives will provide more than 200Tb per second of capacity at speed of 100 GB per second, over 16,000 km.
IAX will not only connect Maldives to the world's content hubs, but it will also support the explosive growth in data demand expected from the new initiatives being launched by the government of Maldives.
The IAX system originates in Mumbai in the west and connects to Singapore, with branches including additional landings in India, Malaysia, and Thailand.

Mysterious New Substance Possibly Discovered Inside Earth's Core

According to a new study, Earth's inner core may be filled with a weird substance that is neither solid nor liquid.
For more than half a century, scientists believed that Earth's deepest recesses consist of a molten outer core surrounding a densely compressed ball of solid iron alloy. But new research offers a rare insight into the inner structure of the planet — and it's far weirder than previously thought.

IIT Roorkee Launches KISAN Mobile to Send Agricultural Advises

The Indian Institute of Technology Roorkee (IIT Roorkee) launched a mobile app named 'KISAN' for the farmers. Through this app, agro-meteorological advisory services will be provided to the farmers.
A farmer's awareness program was organized by IIT Roorkee under the Gramin Krishi Mausam Sewa (GKMS) project. Farmers from Dehradun, Haridwar, and Pauri Garhwal districts took part in this program.
The participating farmers were taught about the Agromet Advisory Services which is jointly provided by the India Meteorological Department (IMD) and AMFU Roorkee.
Agromet Advisory Services are already being provided twice a week to the farmers of six blocks of Haridwar. Through this KISAN app, the bulletins can be accessed via mobile phone.
One unique feature of this app is that advisory bulletin and weather forecasts will be displayed only for that particular block that has been selected by the farmers.
