A Close Planet Orbiting A Star Dubbed As ‘Super-Earth’

The researchers studied the planet by combining measurements from several high-precision instruments mounted on telescopes around the world.

Newly discovered Super-Earth Exoplanet May Sustain Primitive Life

A frozen and dimly lit planet, dubbed a “Super-Earth,” may be orbiting the closest single star to our solar system, astronomers said Wednesday, based on two decades of scientific observations.

The planet, estimated to be at least 3.2 times more massive than Earth, was spotted circling Barnard’s Star, a type of relatively cool and low-mass star called a red dwarf. Barnard’s Star is about 6 light-years away from our solar system, comparatively close in cosmic terms, and it’s believed that the planet obits this star every 233 days.

Planets orbiting stars beyond our solar system are called exoplanets. Nearly 4,000 have been discovered. The newly discovered one is the second closest to our solar system ever found. It is thought to be a “Super-Earth,” a category of planets more massive than Earth but smaller than the large gas planets.

“After a very careful analysis, we are 99 percent confident that the planet is there,” researcher Ignasi Ribas of the Institute of Space Studies of Catalonia and the Institute of Space Sciences said in a statement. “However, we’ll continue to observe this fast-moving star to exclude possible, but improbable, natural variations of the stellar brightness which could masquerade as a planet.”

Alpha Centauri

The only closer stars than Barnard’s Star are part of the triple-star system Alpha Centauri, located a bit more than 4 light-years from our solar system.

Two years ago, astronomers announced the discovery of a roughly Earth-sized planet circling Proxima Centauri, part of the Alpha Centauri system, in an orbit that might enable liquid water to exist on its surface, raising the possibility that it could harbor alien life.

The newly detected planet orbiting Barnard’s Star may not be so hospitable, with surface temperatures of perhaps minus 274 degrees Fahrenheit (minus 170 degrees Celsius). Barnard’s Star provides the frigid planet only 2 percent of the energy that the sun provides Earth.

Space Exploration Critical for our Survival, Says Jeff Bezos

While Elon Musk-led SpaceX always stays in limelight, world’s richest person Jeff Bezos’ aerospace company Blue Origin is fast catching up because for him, “space exploration is critical to our survival”.

In an interview with CBS News along with John F. Kennedy’s daughter Caroline late on Wednesday, Bezos who founded Blue Origin almost 19 years back said he wants his company to be “an instrumental part” of return to the Moon by the US.

“We’re going to be, I hope, an instrumental part of it in cooperation with dozens of companies and governments,” Bezos was quoted as saying.

“To go back to the Moon and the time frame that the administration wants to do, we absolutely need the support of the government to do that,” Bezos said.

In May, Bezos unveiled Blue Origin’s vision for space and also plans for a Moon lander known as “Blue Moon”, set to be ready by 2024.

“I think it is important for this planet. I think it’s important for the dynamism of future generations. It is something I care deeply about,” said Bezos.

The Moon lander “Blue Moon” was in development for three years.

“We must return to the Moon – this time to stay,” the Blue Origin CEO had said.

Bezos revealed that the larger variant of the lander would not only be able to get people on the Moon but also be able to carry the rover to shoot off small satellites and execute scientific missions.

In the near future, Bezos envisions creating enormous space colonies in close proximity to Earth, as a way of expanding humanity to a trillion people.

He envisions fuelling rockets with lunar ice water and using the Moon as the base to explore space further.

“We can harvest that ice and use it to make hydrogen and oxygen, which are rocket propellants,” Bezos said recently. (IANS)
