8 - Helium hydride ion, Universes first molecule detected in space
Helium hydride ion (HeH+), the first molecule that formed almost 14 billion years ago, was detected by NASA's flying observatory SOFIA towards a planetary nebula.
It is the first type of molecule (first molecular bond) that formed in the universe after the Big Bang.
At that time, ionised hydrogen and neutral helium atoms reacted to form HeH+.
Once the universe cooled down, hydrogen atoms started to interact with helium hydride, creating molecular hydrogen, which set the stage for star formation.
From that point on, stars created the other elements of the cosmos.
Despite its importance in the history of the early Universe, HeH+ has so far escaped detection in astrophysical nebulae — cloud of gas and dust in outer space.
9 - Antares Rocket takes off for International Space Station with essential NASA supply
The Antares - a US rocket has been launched from NASA's Wallops Flight Facility on Virginia's Eastern Shore, carrying cargo with the space agency's re-supply mission for the International Space Station (ISS). The rocket was built by Northrop Grumman.
It carried about 7,600 pounds (3,450 kg) of supplies and scientific experiments to the station.
Some instruments it transports will examine astronauts' health in microgravity.
A Canada-made instrument will perform on-orbit detection and quantification of cell surface molecules on a per cell and assess soluble molecule concentration in a liquid sample such as blood, saliva, or urine, thus sparing sample freezing and storing, according to NASA. Another two new experiments will scrutinize aging-like changes in many astronauts on the space station, including changes to their arteries, and examine effects of spaceflight on the function of antibody production and immune memory.
NASA announced it is necessary to take actions to prevent any damage to astronauts in a planned three-year space travel to Mars in 2030s.
10 - Nepal launched its first satellite NepaliSat-1 from US
Developed by the Nepalese scientists, NepaliSat-1 satellite was launched from Virginia in United States. Two Nepali scientists, Aabhas Maskey and Hariram Shrestha who are currently studying at Japanese Kyushu Institute of Technology, developed the satellite under the BIRDS project of their institute.
The BIRDS project has been designed in association with the United Nations and aims at helping countries launch their first satellite. NepaliSat-1 is a low orbit satellite which will be in the 400-km distance from the Earth's surface. It will be stationed at the International Space Station (ISS) for a month and then it will be sent to orbit the earth.
The satellite will take photographs on a regular basis to gather geographical information of the country. Nepal Academy of Science and Technology (NAST) has invested nearly Rs 20 million for the satellite that weighs 1.3 kilograms, a small satellite with limited capability. A group of four engineering graduates were also working to launch another Nepali satellite 'Nepal PQ-1' in 2020.
11 - NASAs TESS found first Earth sized world
The Transiting Exoplanet Survey Satellite (TESS) Mission of NASA has discovered HD 21749c, first Earth-sized world.
About HD 21749c
The planet, HD 21749c, is about 89% of Earth's diameter. The planet orbits HD 21749, a K-type star with about 70% of the Sun's mass located 53 light years away in the southern constellation Reticulum. HD 21749c is the second planet TESS has identified in the system. HD 21749c is the 10th confirmed planet discovered by TESS, and hundreds of additional candidates are now being studied.
HD 21749c doesn't seem to have good life-hosting potential as it circles its host star very tightly, completing one orbit every 7.8 Earth days, and is therefore probably quite hot. TESS which was launched just about a year ago is already a game-changer in the planet-hunting business. TESS total tally is likely to end up topping that of Kepler has found about 70% of the 4,000 exoplanets discovered to date.
12 - Sri Lanka launched its first Satellite
Sri Lanka's first satellite Raavana l was launched into space from NASA's Flight Facility on Virginia's east shore. The satellite was designed and developed by two Sri Lankan engineers at the Kyushu Institute of Technology in Japan. It will be shuttled to the International Space Station. The “Raavana 1” was launched into space with the assistance of the US rocket “Antares”. About Raavana l: Raavana 1 weights around 1.05 kg and is 1000 cubic centimetres in size. The minimum lifespan of the satellite is around one and a half years and it is expected to be active for five years. Raavana 1 satellite's camera mission is to capture images of Sri Lanka and its neighbouring countries. The Raavana-l is expected to orbit 400 kilometres away from the earth. The satellite will achieve an active attitude stabilization which ensures that the satellite's attitude is stable under the influence of external talks. The launch of Raavana-l marks Sri Lanka's entry into the global space age.
13 - World's largest airplane weighing 2,26,800 kg took its first ever flight

15 - Scientists discovered chain melted state of matter
Scientists from the University of Edinburgh of Scotland while examining potassium have discovered a new state of physical matter where atoms can exist as both solid and liquid at the same time known as the chain melted state. The discovery was made using powerful computer simulations.
At the chain-melted state, atoms are both solid and liquid at the same time. Scientists have discovered that when extreme pressure and temperature are applied to potassium, it can form a state in which most of the atoms form a lattice structure but a second set is in a fluid arrangement.
Scientists say that it would be like holding a sponge filled with water that starts dripping out, except the sponge is also made of water. Over half a dozen elements including sodium and bismuth are thought to be capable of existing in the newly discovered state. Researchers hope it can be further examined to find more uses for the unexpected discovery.

18 - Scientists warn of amphibian pandemic that already killed 90 species
A deadly disease affecting amphibians has descended into a global pandemic and it has already wiped out 90 species.
This was disclosed by a prominent US biologist Jonathan Kolby, at the World Organisation for Animal Health Aquatic Conference in Santiago, Chile yesterday. The disease attacks the skin of frogs, toads and other amphibians.
As the creatures use their skin to breathe and regulate their bodies' water levels, the damage caused by the disease eventually leads to heart failure and death.
Over the past five years, the highly contagious disease has already caused nearly 90 species to disappear, with over 500 impacted.
