Name the telescope, which is used by astronomers to capture the first image of Black Hole?

21 light years away on december 22, 2018 in the constellation Cassiopeia, a shimmering "super-Earth", five times the mass of Earth, dubbed as HD219134 b was discovered. Unlike the Earth, however, it most likely does not have a massive core of iron, but is rich in calcium and aluminium alongside magnesium and silicon. It shimmers red to blue like rubies and sapphires, because these gemstones are aluminium oxides which are common on the exoplanet. According to the researchers it is one of three candidates likely to belong to a new exotic class of exoplanets. The other two exoplanets studied were 55 Cancri e and WASP-47 e. The study was published in the journal Monthly Notices of the Royal Astronomical Society: Letters.

NASA's first mission to demonstrate a planetary defence technique, The Double Asteroid Redirection Test (DART), will get one opportunity to hit small moonlet in the binary asteroid system Didymos. The asteroid poses no threat to Earth and is an ideal test target. NASA revealed that details about its plan to hit a small moonlet target in a double asteroid system with a spacecraft in 2022. The asteroid, called Didymoon or Didymos B, is a moon asteroid around 150 meters tall orbiting a larger body Didymos A, the most accessible asteroid of its size from the Earth.

Recently, Indian and the US navies conducted joint submarine hunting exercise near Diego Garcia in the Indian Ocean in which India's P8I Neptune Aircraft and US P-8A Poseidon maritime patrol aircraft along with the USS Spruance have participated. The objective of this exercise is to lay the groundwork for coordinating maritime patrol and reconnaissance.The Indian P-8I anti submarine aircraft which participated in the exercise is from Naval Air Squadron 312 based at Naval Station Rajali in Arakkonam, Tamil Nadu and US P-8A Poseidon aircraft which participated in the exercise is from Patrol Squadron VP-8 'Fighting Tigers', based in Jacksonville, Florida.

The Indian Space Research Organisation (ISRO) has recently launched Samwad with Students as part of its outreach programme. The Indian Space agency will engage youngsters across the country in activities concerning space science under this programme. The new conversation mission will inspire students cutting across schools and colleges. During the inauguration in Bengaluru, 40 students and 10 teachers from select schools interacted with ISRO Chairman Dr. K Sivan about the Indian Space Programme and their benefits to the common man.

The Northrop Grumman Antares rocket and its unscrewed Cygnus Spacecraft launched which contains tons of NASA's supplies and 40 live mice to the International Space Station (ISS), from the Mid-Atlantic Regional Spacecraft at NASA's Wallops Flight Facility on Wallops Island in Virginia. The first stage of rocket was developed by the Ukrainian Yuzhnoye State Design Office. The mission named NG-11, is the 11th cargo flight for NASA by Northrop Grumman, to deliver 7600 lbs. (3,447 kg), the heaviest load for Cygnus till date which contains science gear and supplies to the sex person crew of the ISS. This mission will be the Northrop Grumman's longest one till date.

Indian Space Research Organisation's (ISRO) first mission of 2019, Microsat-R, is to be launched into space on 24th January 2019. The 130-kg Microsat-R is a military imaging satellite. Microsat-R and its payload come assembled from a handful of laboratories of the Defence Research and Development Organisation (DRDO) and is meant for military use. The satellite was assembled outside and ISRO only interfaced it with its own systems and the launch vehicle, just as it treats any customer satellite. PSLV-C44 will be launched from the older First Launch Pad at the Satish Dhawan Space Centre, Sriharikota in Andhra Pradesh. For its part, ISRO is experimenting on two aspects of the vehicle. One is to reuse a waste stage.

In a first, The Indian Space Research Organisation (ISRO) opened a visitors' gallery with 5,000 capacity at Andhra Pradesh's Sriharikota island. The gallery has a clear line of sight to two launch pads and large screens to explain launcher and satellite features. This comes as ISRO is launching defence satellite EMISAT along with 28 foreign satellites on April 1, 2019.

Israeli lunar mission Beresheet crashed on the Moon. Beresheet crashed during a landing attempt. It is said that the spacecraft had problems with its main engine during its descent that left it unable to slow down in time before it smashed into the lunar surface. Beresheet was an Israeli mission launched by a partnership between nonprofit SpacelL and government-owned aerospace company Israel Aerospace Industries. It is the World's first privately funded lunar Mission. It was a demonstrator of a small robotic lunar lander. Its aims included promoting careers in science, technology, engineering, and mathematics (STEM); and landing its magnetometer and laser retroreflector on the Moon. Beresheet lander had carried a science instrument provided by NASA, a retroreflector instrument scientists would have used to make precise measurements of the distance between Earth and the moon.

Transiting Exoplanet Survey Satellite (TESS), NASA's latest planet-hunting probe, has discovered a new world outside our solar system, orbiting a dwarf star 53 light years away. This is the third new planet confirmed by TESS since its launch in April 2018. The planet has been named as HD 21749b. The planets orbits a bright, nearby dwarf star about 53 light years away, in the constellation Reticulum, and appears to have the longest orbital period of the three planets so far identified by TESS.

Astronomers from the University of Texas at Austin, in partnership with Google have discovered two hidden planets in the data collected by the Kepler space telescope. They have created an algorithm that has explored the data taken by Kepler to find out signals that were missed by traditional planet-hunting methods.K2-293b - It orbits a star 1,300 light-years away in the constellation Aquarius. K2-294b - It orbits a star 1,230 light-years away, also located in Aquarius. They both are hot planets and have short orbital periods. They are slightly larger than Earth. They are discovered from the Kepler's extended mission, called K2.
