Astronomers have discovered a potential key step in the chemical process that occurs in “stellar nurseries,” which are clouds of gas and dust in space that eventually form young stars and planets.

Two Earth sized Planets Orbit a Red-dwarf: GJ 1002 System
In an international collaboration between astronomers, two planets orbiting a red-dwarf star have been identified. The planets, GJ 1002 b and c, are 16 light-years away and about the size of Earth. Both lie within the star’s habitable zone. Which means, the orbital distance is enough to allow liquid water to form on the surface provided it has the right kind of atmosphere.
Read MoreBook Review: Tau Zero by Poul Anderson
My favourite thought experiment is the notion that as an individual approaches the speed of light, time slows down. Now let’s extrapolate it to Big Crunch scenario. What if an individual travel at the speed of light and reaches the end of universe? According to Russian Physicist Alexander Friedmann, end of the universe depends on its density. Therefore, universe cannot stay stable for ever, it could either expand or contract. Gravity, with the help of matter, could slow down the expansion, then stop, and ultimately reverse it. Everything collapses within…
Read MoreActive Mantle Plume on Mars: Martian Geodynamic Evolution
Cumulative evidence, so far has suggested that Mars once had oceans but then lost its atmosphere and eventually died out. Unlike Earth, where shifting tectonic plates make way for dynamic interior, Mars never surfaced such processes. Hence, the astronomers concluded that nothing much happened on the red planet, at least, in the last 3 to 4 billion years. Recent observations by the scientists at the University of Arizona, however has challenged the current views of Martian geodynamic evolution. As per them, the red planet, that seems to be dead, has an…

Astronomers work ceaselessly to find out clues that might point out to the existence of extra-terrestrial life some where in outer space. The mere idea that we might not be alone is enough motivation to work constantly in this hunt. Lately, there has been an increase in the number of research probing into exoplanets. In one such research, astronomers have discovered a super-Earth like planet near the habitable zone of a red dwarf star. It is about 37 light-years from the Earth. This also happens to be the first such…
Read MorePeriodic Pattern of Fast Radio Bursts Detected from Another Galaxy: Mysterious Space Signals
Astronomers at MIT and Canada have traced a periodic radio signal coming from a distant galaxy. The signal is quite intense and hence, fall under the category of fast radio burst a.k.a FRB. Usually, FRB lasts for about a few milliseconds, however, the newly discovered signal has continued for three seconds. During this time frame, the astronomers also traced bursts of radio waves that reiterated every 0.2 seconds in a distinct periodic pattern. The rhythming pattern of the radio waves resembled a beating heart.
Read MoreMoon Soil Can Grow Terrestrial Plants: Tiny Lunar Garden
For the first time in human history, space scientists were able to grow plants in the soil from the moon. With the plants sprouting from the moon soil, lunar exploration seems pretty incredible. University of Florida researchers were able to prove that moon soil – also called as lunar regolith – can grow terrestrial plants. They also investigated that for the plant it wasn’t an easy journey. Nevertheless, this effort is the first step towards understanding how plants respond biologically to the Moon’s soil. This insight will surely help NASA’s…
Read MoreTwo Rocky Worlds Orbiting M Dwarf Star: The HD 260655 System
Astronomers at NASA have identified two rocky alien worlds hovering around M dwarf star called HD 260655. M stars have faint glow and they look red to our eyes with temperature ranging from 2,500 Kelvin to 3,500 Kelvin. These stars account for nearly 75% of the stars in our stellar neighborhood, which implies they can be easily observed from Earth due to its abundance. As per Transiting Exoplanet Survey Satellite (TESS), the newly discovered exoplanets are about two times more massive than the Earth.
Read MoreTwo Neutron Stars could give Birth to a Third: Stellar Formation
An international team of astrophysics from Manly Astrophysics and Universidad de Murcia has proposed for a new type of exotic neutron star. According to astronomers Arthur Suvorov and Kostas Glampedakis, the novel neutron star could be the result of a super strong magnetic field that emanates during a collision between old neutron stars.
Read MoreHuge Gas Planet Hidden in Plain Sight: TOI-2180 b
Hunt for a new stellar body is always on. Space is full of astronomical bodies and star gazers continuously search for new stars and planets into the known realm of humanity. In one such effort, an astronomer at University of California, Riverside in collaboration with a group of citizen scientists have spot a huge gas planet. The newly discovered body is otherwise hidden from view by typical stargazing tools.
Read MoreBook Review: Contact by Carl Sagan
Last year I saw the movie, Contact. And I found the plot very propulsive, so decided to read the book written by Carl Sagan. Like a teenager, I’m equally fascinated with the idea of space exploration and extra-terrestrial life/intelligence. And reading Contact was surely a treat.
Read MoreStellar Streams’ Trajectory Reveals the Dark Matter: Mysterious Universe
Understanding the properties of dark matter is the most important quest for astronomers. Many have dedicated their years to research just to take a sneak peek into what actually comprises of dark matter. In a recent research, astronomers have detected twelve streams of stars spiralling within the outermost region of our galaxy.
Read MoreVenus could be a Life-bearing Planet: Space Exploration
Space scientists have always looked up to our closest planet neighbour and wondered what if there is life on Venus. Sanjay Limaye, from University of Wisconsin-Madison Space Science also an expert on Venus says that in the coming decade in a collective effort, astronomers all across the globe will make case for exploring the “evening star”. With an experience of over 45 years, Limaye’s core investigation is the planet’s dense atmosphere.

The Moon is a Harsh Mistress happens to be my first peek into Heinlein’s work. The book is embedded with wonderful interstellar imagination – artificial intelligence, extra-terrestrial colonization, and interplanetary warfare.
Read MoreBiofuel to Produce Locally on Mars: Martian Exploration
What if we are able to produce fuel directly on Mars? Explorers would then be able to stay on the red planet a li’l longer and return journey will then be easier relatively. Shipping the propellant and oxygen for a return journey from Mars would cost billions of dollars. To make things easier, researchers have developed a concept for local rocket fuel production with algae and E.coli.
