Astronomers Discover A New 'Beast' Class Transient Object

Back in 2016, astronomers observed a cosmic explosion within a tiny galaxy 500 million light-years. In a new study, the explosion was found to be a new class of object that is one of the biggest cosmic bursts recorded yet.

Senior author of the study, Raffaella Margutti from Northwestern University says, “There is a new beast out there, and it’s able to produce the same energetic phenomenon” as the collapse of a massive star or the merger of two neutron stars.

The explosion, CRTS-CSS161010J045834-081803 was found to be a fast blue optical transient object or simply, an FBOT. It is located in a dwarf galaxy near the constellation Eridanus that hosts about 10 million stars, a lot less compared to our Milky Way Galaxy. Its location is similar to other FBOT objects that have been found in dwarf galaxies as well but the newly discovered transient object was the biggest yet.

AT2018COW, nicknamed ‘The Cow’, is one such rare FBOT event that is thought to have occurred during the birth of a neutron star or a black hole. These cosmic explosions are initially detected in the optical wavelength as they glow blue because of their high temperatures. The cosmic bursts then rise until they reach the peak of brightness following which, they start to decay. This happens at rates comparatively faster than standard supernovae.

Indian Regional Navigation Satellite System (IRNSS) : NavIC

IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East. IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users. The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area. Some applications of IRNSS are: Terrestrial, Aerial and Marine Navigation Disaster Management Vehicle tracking and fleet management Integration with mobile phones Precise Timing Mapping and Geodetic data capture Terrestrial nav

10 Free Website Builders:

1. Webnode – Modern Editor with Some Limitations A short while ago Webnode completely revamped their editor, making it very modern. The themes they added are stylish and responsive. A pity you can’t choose a completely new theme after your initial choice. Working with Webnode is very intuitive and also here (surprise) you have the option of upgrading to a paid plan. Webnode offers a low-cost variant at $3.95 per month (which they fittingly call Limited ) essentially allowing you to use a domain name you already own and to contact their premium support. The small ad will stay with this option. Unfortunately, there is no ecommerce option in the free plan and also the blog is very basic. 2. Wix – The International Heavyweight The biggest of them all is Wix. They have more users than any other site builder and it’s easy to see why. It’s packed with unique features and great templates. According to our tests , it’s the best choice to create a paid site – but what about a free one?

NASA Mars Flight

he helicopter will rise for about six seconds, hover and rotate for about 30 seconds, then go back down. The flight will be autonomous, pre-programmed into the aircraft because of the 15 minutes it takes for signals to travel from Earth to Mars. Ingenuity itself will analyze its position with respect to the Martian surface. After the flight, Ingenuity will send Perseverance technical data on what it has done, and that information will be transmitted back to Earth. This will include a black and white photo of the Martian surface that Ingenuity is programmed to snap while flying. Later, once its batteries have charged up again, Ingenuity is to transmit another photo -- in color, of the Martian horizon, taken with a different camera. But the most spectacular images are supposed to come from the rover Perseverance, which will film the flight from a few meters away. Shortly after this filming, six videos of 2.5 seconds each will be sent to Earth. NASA hopes at least one of them will show th
