Name the new dwarf spheroidal galaxy discovered by astronomers from Italy, the UK, Germany and the United States, using Hubble Space Telescope, on 31st January 2019?

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.

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.

Karnataka's swimmer Srihari Nataraj has emerged as the most prolific gold medal winner at the Khelo India Youth Games. He has won 7 Gold medals in swimming events. P Likith from Karnataka won five gold medals and a bronze medal in swimming at the Khelo India Youth Games. They both were the most decorated gold medalists of the Games.

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.

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.

China launched two Tianhui II-01 satellites from Taiyuan Satellite Launch Centre, also known as Base 25. The purpose of the satellite is to perform scientific experiments, land resource and geographic survey, and mapping. The satellites were launched by a Long March 4B carrier rocket also known as Chang Zheng 4B. This was the 303rd successful mission of the Long March series carrier rocket.

Space Exploration Technologies Corp. (Space X) launched its 17th commercial resupply mission to the International Space Station (ISS) by using Falcon 9 rocket with Dragon Spacecraft. The 213-foot-tall rocket lifted off from Cape Canaveral Air Force Station in Florida. This mission is a part of NASA's Commercial Resupply Services (CRS) program, which uses commercial spacecraft to deliver cargo to the ISS.

ISRO Planning to Launch 32 Space Missions in 2019. The missions include the second lunar mission Chandrayaan-2 (Rs.800-crore mission) to land on the moon with lander and rover. India's maiden human space mission in 2021-22, Gaganyaan, will also be pursued this year. Among the ISRO's achievements in 2018 were launch of the heaviest satellite GSAT-29 (3,423 kg) on November 14 and building the heaviest communication satellite GSAT-11 (5,854 kg), launched on December 5 onboard the Arianespace space agency's rocket from French Guiana on the north Atlantic coast of South America.
