This is after nine years of observing, after a malfunctioning steering system required a complex fix and change of plants, and after the hydrazine fuel levels reached empty. NASA officials announced on Tuesday that the pioneering exoplanet survey telescope - which had led to the identification of almost 2,700 exoplanets - had finally reached its end, having essentially run out of fuel. As of October 2018, the planet-hunting spacecraft has been in space for nearly a decade. “But we think Hycean planets offer a better chance of finding several trace biosignatures.”Ĭo-author Anjali Piette, also from Cambridge, added: “It’s exciting that habitable conditions could exist on planets so different from Earth.”Īn illustration of the Kepler Space Telescope, which is on its very last legs. “Essentially, when we’ve been looking for these various molecular signatures, we have been focusing on planets similar to Earth, which is a reasonable place to start,” he said. Hycean planets, Madhusudhan said in a release, offer a new paradigm for the search for life beyond Earth. Many of the prime Hycean candidates identified by the researchers are bigger and hotter than Earth, but the researchers argue that they still have the characteristics to host large oceans that could support microbial life similar to that found in some of Earth’s most extreme watery environments. “Hycean planets open a whole new avenue in our search for life elsewhere,” said Nikku Madhusudhan from Cambridge’s Institute of Astronomy, who led the research. They call them Hycean planets due to the presence of substantial hydrogen in the atmospheres and large oceans (hydrogen and ocean = Hycean) on their surfaces.Īnd in an article in The Astrophysical Journal, they make the case that under certain conditions, some Hycean planets could, indeed, be habitable. There are rocky planets, water worlds, gaseous planets, super-Earths, hot Jupiters, tidally locked planets, planets in orbital resonance with each other, and so much more.Ī group of exoplanet researchers at the University of Cambridge have recently proposed a new category of planet, one that has seldom been considered even potentially habitable.

Planets beyond our solar system, we now know, come in all shapes, sizes and consistencies. (Artist rendering by Amanda Smith, University of Cambridge) The image features a red dwarf star as the planet’s host star. A new report from the University of Cambridge suggests this kind of planet, sized between a super-Earth and a mini-Neptunes, could potentially support life. Both of these values are given in arcseconds.įor example, to have a ring-like mask between 0.5 and 2.A so-called Hycean planet is one featuring large oceans and a hydrogen atmosphere. The r_min and r_max arguments allow you to tailor the masks inner and outer radii to the emission that you observe. There are a few additional options to make a better fitting mask to your data. This command will produce a new file, image_, which is the mask which can be passed to future tclean calls or exported as a FITS file. mstar is the stellar mass in solar masses, dist is the source distance in parsec and vlsr is the systemic velocity in meters per second. Hopefully the parameters are obvious, but for clarity, inc is the disk inclination in degrees, PA is the disk position angle in degrees, measured from North to the redshifted major axis in an anti-clockwise fashion.
