Read our privacy policy Astronomers have discovered a cold brown dwarf – otherwise known as a “super planet” – for the first time using a radio telescope. While brown dwarfs do not undertake fusion reactions, they do emit light at radio wavelengths in a similar way that Jupiter does – accelerating charged particles like electrons to produce radiation including radio waves and aurorae. “We asked ourselves, ‘Why point our radio telescope at catalogued brown dwarfs?’” said Harish Vedantham, lead author of the study and astronomer at ASTRON. This discovery could also help astronomers measure exoplanets’ magnetic fields, as cold brown dwarfs are the most similar bodies to exoplanets that scientists can measure with radio telescopes.

Mysterious radio signals originating from distant stars could hint at possible hidden planets

Firstpost  

The researchers are confident that the signals are coming from the magnetic connection between the dwarf stars and the hidden planets in their orbit. In a major discovery, scientists have found radio waves emitting from distant stars, possibly indicating the existence of hidden planets. According to Pope, the research “could potentially lead to the discovery of planets throughout the galaxy.” …

First-ever radio signal from 51 light years away from the earth

The Hindu  

Using Low Frequency Array, a radio telescope, in the Netherlands, a team of researchers from Cornell University discovered emission bursts from the Tau Bootes exoplanet system, 51 light-years away from the earth. The detected radio signals could be the first-ever radio emission from a planet beyond our solar system, the team said. “We present one of the first hints of …

Citizen scientists help discover 95 brown dwarfs that are neighbors of our sun

CNN  

CNN — Our sun may not be so alone after all. The brown dwarfs don’t have quite enough mass to sustain nuclear reactions in their core that power stars, so they’re more like cooling embers, according to researchers at the National Science Foundation’s NOIRLab. “These Backyard Worlds discoveries show that members of the public can play an important role in …

A cold Neptune and two super-Earths are among newly found exoplanets around nearby stars

CNN  

CNN — Five exoplanets and eight planet candidates have been found around nearby stars, including a “cold Neptune” and two super-Earths that are potentially habitable, according to a new study. The two super-Earths, GJ180d and GJ229Ac, were found around small red dwarf stars that are 19 and 40 light-years away from our sun, while the cold Neptune was found around …

NASA space telescopes 'Spitzer' and 'Swift' discover elusive brown dwarf

India TV News  

A unique collaboration between NASA's Spitzer and Swift space telescopes have led to a discovery of a new brown dwarf - thought to be the missing link between planets and stars, with masses up to 80 times that of Jupiter. The discovery of this brown dwarf, with the unwieldy name OGLE-2015-BLG-1319, marks the first time two space telescopes have collaborated …

Huff Post  

Chuck Carter and Gregg Hallinan/Caltech For the first time ever, the celestial light shows known as auroras have been detected outside our solar system. "If you were able to stand on the surface of the brown dwarf we observed--something you could never do because of its extremely hot temperatures and crushing surface gravity--you would sometimes be treated to a fantastic …

Know about the innovative instrument which can picture exoplanets

India TV News  

New Delhi: An exoplanet is a planet outside the Solar System. For centuries philosophers and scientists supposed that extrasolar planets existed, but there was no way of detecting them. The first confirmed detection of exoplanet came in 1992, with the discovery of several terrestrial-mass planets orbiting the pulsar PSR B1257ი.Now till date more than a thousand such planets have been …
