Oscars of science awarded to Event Horizon Telescope Team: 

The Event Horizon Telescope Team consists of 347 scientists produced the world first image of a black hole. They were felicitated with breakthrough Prize in Fundamental Physics. The prize is known as the Oscars of science with prize money $3 million. The team published the image of black hole circled by a flame-orange halo of white-hot plasma on the Messier 87 (M87) galaxy.

Directed by Shep Doelman at the Harvard-Smithsonian Center for Astrophysics, the team spent over a decade simulating an Earth-sized computational telescope that combined the signals received by eight radio telescopes working in pairs around the world with their sights trained on the Messier 87 (M87) galaxy, 55 million light-years away.

Through this technique, they were able to achieve an unprecedented resolution and observe the black hole`s silhouette for the first time in history, confirming theoretical predictions about these celestial objects.

The event horizon of a black hole is the point at which its gravitational effects are strong that light cannot escape its pull.

The Breakthrough Prize was launched by Silicon Valley entrepreneurs to recognize and reward the world`s top scientists.

They will be recognized at a gala awards ceremony on November 3, at NASA Ames Research Center in Mountain View, California.

Chandrayaan 2 Lander has been located in Moon:

Chandrayaan-2`s Lander module Vikram has been located on the lunar surface. The Lander was located by the image sent captured by the on-board camera of Chandrayaan-2 orbiter. The image also showed that rover Pragyan is housed inside it. The Indian space agency also said the data that was received is being analyzed.

Orbiter:

The camera of the orbiter has the highest resolution camera of 0.3m in any lunar mission so far. It is expected that it will provide high-resolution images which will be immensely useful to the global scientific community. 

The orbiter has 8 payloads to map the lunar surface and study the outer atmosphere of the Moon. The payloads of the Orbiter will conduct remote-sensing observations from a 100 km orbit.
