Karnataka's swimmer Srihari Nataraj has emerged as the most prolific gold medal winner at the Khelo India Youth Games. How many gold medals he won?

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.

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.

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.

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.

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.

A group of researchers, led by astronomers at San Diego State University, by using data from NASA's Kepler Space Telescope, detected the new Neptune-to-Saturn size planet orbiting between two previously known planets Kepler-47b and Kepler-47c. This new planet named as Kepler-47d. The research was recently published in the Astronomical Journal.According to a new study, Kepler-47d is about seven times larger than Earth and also the largest of the three planets in the Kepler-47 circumbinary system. The Kepler-47 system is approximately 3.5 billion-years-old and it is 3,340 light years away in the direction of the constellation Cygnus.

NASA has announced a new space telescope mission dedicated to understanding the origins of life and the universe. It's called the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer or SPHEREx, for short. The space agency is aiming for a 2023 launch. Once SPHEREx is in orbit, it will observe and collect data on over 300 million galaxies, some as far as 10 billion light-years away from Earth, and 100 million stars in our own Milky Way every six months. The space telescope's main goals, though, are to search for water and organic molecules within the Milky Way. It will also look for those ingredients of life in regions where stars are born.

On January 31,2019, astronomers from Italy, the UK, Germany and the United States discovered newly discovered galaxy consists of red giant particles. Bedin 1 is a new dwarf spheroidal galaxy. This ancient galaxy is one of the oldest galaxy and was named after Luigi Bedin, a researcher at Italy's National Institute for Astrophysics. Bedin 1 is located 28.38 million light years from Earth.

India successfully completed 'Mission Shakti' operation where it destroyed a live satellite on a low earth orbit (LEO) using an Anti-Satellite (ASAT) missile in three minutes. India has become the 4th country after the US, Russia and China in the world to achieve this historic feat. Anti Satellite weapons also called the ASAT are developed to destroy satellites. Mission Shakti is a joint programme of DRDO and the Indian Space Research Organisation (ISRO). Mission Shakti will help the country in standing strong and secure. It will further protect the nation from disharmony and bring peace.

The Indian Space Research Organisation (ISRO) has launched a Defence Intelligence Satellite, EMISAT in its 47th Polar Satellite Launch Vehicle (PSLV) mission, along with 28 other customer satellites, onboard the advanced PSLV-C45 Rocket. The PSLV C45 was launched from ISRO's Satish Dhawan Space Centre in Sriharikota. It is the first time ISRO is launching satellites in three different orbits. Along with that, the PSLV-C45 launch vehicle is also the first PSLV rocket to use four strap-on motors.
