Second Earth Proxima B

Second Earth, Proxima b, discovered by scientists, is a game-changer

A “second Earth,” orbiting our planet’s closest star may have the right conditions to sustain alien life forms, astronomers have revealed. The mystery world spotted by experts at the European Southern Observatory may finally answer if we are alone in the universe. The planet circles the “goldilocks zone” of Proxima Centauri, the red dwarf star just four light years away.
Star Radiation

Suntan and alien radiation: Ten trillionth of one's suntan is intergalactic radiation, world-first study confirms

In a world-first study, Australian researchers have calculated the proportion of our suntan that comes from beyond the Milky Way. This skin-tanning, natural radiation comes not from the sun but distant hungry black holes and stars and is known as intergalactic solarium. This alien radiation is also known as extra-galactic background light that that gives the tan. This alien light well beyond our galaxy helps beachgoers get that tanned bronze.
Venus

Sun turned once-habitable Venus to hell

NASA thinks Venus may have looked like Earth once. It was a planet capable of life, with a shallow liquid-water ocean and habitable surface temperature for up to two billion years.
Aurora Borealis

Australian mini-satellites to explore Earth's thermosphere; 3 Australian universities to make history

Australian researchers are taking a historic step forward as the Qb-50 project is set to launch its first Aussie mini-satellites in space from International Space Station (ISS) next year. The project will study Earth’s thermosphere as it is the least-understood layer of our atmosphere. Researchers from three Australian universities are getting ready to make history as they prepare to measure the density and temperature of plasma in that region.
Milky Way

Milky Way's core is a cosmic desert with no new stars, astronomers discover

Astronomers have reportedly discovered the most-desolate place in the Milky Way. The vast expanse right at the centre could well be a cosmic desert that is completely devoid of young stars. The new study by the international team of researchers promises to better the understanding of the entire Milky Way.
Perseid Meteor Shower

Perseid meteor shower Australia: Stargazers must head north to witness cosmic magic

It will be a double delight for stargazers as North Wales would allow them a chance to not only witness the Perseid meteor shower but also spot Jupiter, Saturn, Mars, Venus and Mercury this August. The five planets would be aligned along with the famous Perseid meteor shower, a perfect treat for stargazers.
Sun

Newly-discovered planet with 3 suns in faraway solar system

An international team of scientists have recently discovered a strange planet in a faraway solar system that has not one but three suns. The planet, named HD 131399Ab, is way weirder than Luke Skywalker’s home planet Tatooine in the Star Wars saga that orbited around two suns.
Saturn

Titan may host non-water-based life

NASA's Huygens and Cassini missions have revealed that Saturn’s moon Titan may support non-water-based life. The missions provided invaluable data on chemical elements found on Titan, and Cornell scientists have been able to find a chemical trail that suggests that prebiotic conditions may exist there.
Mercury

Mercury's surface formed when volcanic activity spewed up materials from the core

Lab experiments have revealed that the chemistry of Mercury’s most ancient plains was likely forged near the planet’s core. NASA researchers said that Mercury’s surface feature originated from intense heating and crushing of rock 400 kilometres down, where the planet’s mantle meets the iron core.
Mercury

Rare meteorite on Earth points towards Mercury's origins

MIT geologists have studied part of planet Mercury’s cooling history right after it formed between 4.2-3.7 billion years ago and traced its origins to an enstatite chondrite, a rare meteorite. This kind of meteorite is extremely rare on Earth.
Gravitational Waves

Gravitational waves in space may reveal how supermassive black holes formed

Scientists led by Durham University's Institute for Computational Cosmology captured gravitational waves via space-based detectors, and now they believe that these waves can help identify the origins of supermassive black holes. The scientist ran massive cosmological simulations that may be used to predict the rate at which gravitational waves caused by collisions between the monster black holes might be detected.
Mars

Dutch researchers raise peas, radishes, tomatoes and rye on simulated Martian soil

Researchers from Wageningen University in the Netherlands have revealed that cereals and vegetables they grew in “Martian” soil for two years are safe for human consumption. The Dutch researchers successfully raised peas, radishes, tomatoes and rye in soil that was made to match that of the red planet. This has provided researchers the hope of growing food on Mars. The food grown was found to contain “no dangerous levels” of heavy metals.
Supermassive Black Hole

Dormant black hole suddenly becomes active to devour passing star; X-rays from inner part of disk baffle scientists

Astronomers from the University of Michigan and University of Maryland have for the first time mapped the flow of gas near a supermassive black hole, Swift J1644+57, that woke from its dormant state to destroy and devour a star that drifted close to it. The astronomers are the first to document X-rays bouncing from deep within the walls of the black hole’s newly-formed accretion disk after a tidal disruption event.
