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.

According to our tests , it’s the best choice to create a paid site – but what about a free one?

Coronavirus Symptoms,Transmission,Prevention,Treatment

Symptoms:- Common human corona viruses Common human coronaviruses, including types 229E, NL63, OC43, and HKU1, usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with these viruses at some point in their lives. These illnesses usually only last for a short amount of time. Symptoms may include runny nose headache. cough sore throat fever a general feeling of being unwell Human coronaviruses can sometimes cause lower-respiratory tract illnesses, such as pneumonia or bronchitis. This is more common in people with cardiopulmonary disease, people with weakened immune systems, infants, and older adults. Transmission :- Human coronaviruses most commonly spread from an infected person to others through the air by coughing and sneezing close personal contact, such as touching or shaking hands touching an object or surface with the virus on it, then touching your mouth, nose, or eyes before washing yo
