Sun erupts with 17 flares, solar storms to hit Earth on Thursday
At least 17 solar eruptions from a single sunspot on the sun have blasted into space in recent days, and may reach Earth as moderate geomagnetic storms by Thursday. The sun eruptions originated from an overactive sunspot, called AR2975, which has been firing off flares since Monday (March 28). The stellar event may also cause some moderate sky storms on Earth, Space.com reported.
NASA confirms existence of over 5,000 exoplanets
The planetary odometer turned on March 21, with the latest batch of 65 exoplanets - planets outside our immediate solar family - added to the NASA Exoplanet Archive. The archive records exoplanet discoveries that appear in peer-reviewed, scientific papers, and that have been confirmed using multiple detection methods or by analytical techniques.
Astronomers find no signs of Planet Nine
A team of astronomers who scammed about 87 per cent of the southern sky have found no trace of Planet Nine in our solar system yet. Pluto, discovered in January 1930, was earlier known as the Planet Nine. However in 2006, astronomers reclassified Pluto as a dwarf planet. Although ACT was designed to study the cosmic microwave background radiation, its relatively high angular resolution and sensitivity makes it suitable for this type of search.

James Webb Telescope shares 1st view of cosmos
Webb's team now expects that the telescope's optical performance will be able to meet or exceed the science goals the observatory was built to achieve. The team completed the stage of alignment known as "fine phasing" on March 11. With the fine phasing stage complete, the team fully aligned Webb's primary imager, the Near-Infrared Camera, to the observatory's mirrors.
Indian scientists refute US researchers' claim of radio wave signal from cosmic dawn
A team of researchers from Arizona State University (ASU) and MIT in the US had in 2018 detected a signal from stars emerging in the early universe using data from the EDGES radio telescope. The study published in journal Nature had then created much excitement in the astronomy community around the world.
Scientists reveal 4.4 million galaxies in new map
The map reveals an astonishingly detailed radio image of more than 4.4 million objects and a very dynamic picture of our Universe, which now has been made public for the first time. The vast majority of these objects are billions of light years away and are either galaxies that harbour massive black holes or are rapidly growing new stars.
Cancer cure: BHU scientists develop new variety of Rishyagandha
Banaras Hindu University (BHU) scientists have developed a new variety of medicinal plant Rishyagandha which has the properties to treat all types of cancer, especially cervical.
