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.

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.

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…

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.

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.

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.

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.

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.
