Swiss nerds to launch exoplanet measuring CHEOPS space telescope next year

November 14, 2018

Swiss nerds are awesome.  They were the ones to discover the first exoplanet in 1995.  In 2019, CHEOPS will be launched in order to measure the radii of exoplanets.  When radius and mass are known, the density of the planet can be calculated.  Here’s a boring video about the making of CHEOPS.  2019 will also reveal the early results of TESS to the public.

UPDATE: Kepler K2 3.5 years and counting

February 10, 2018

UPDATE 8.08.18:

Based on data from NASA’s K2 mission, an international team of scientists has confirmed 44 new exoplanets. This brings the total number of new exoplanets found with the K2 mission up to 347.

“We started out analyzing 275 candidates, of which 149 were validated as real exoplanets. In turn, 95 of these planets have proved to be new discoveries,” said U.S. doctoral student Andrew Mayo at the National Space Institute (DTU Space) at the Technical University of Denmark. “This research has been underway since the first K2 data release in 2014.”

Shot of ESPRESSO seeking life

December 7, 2017

5-firstlightfoThe Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations (ESPRESSO) has successfully made its first observations. Installed on ESO’s Very Large Telescope (VLT) in Chile, ESPRESSO will search for exoplanets with unprecedented precision by looking at the minuscule changes in the light of their host stars. For the first time ever, an instrument will be able to sum up the light from all four VLT telescopes and achieve the light collecting power of a 16-meter telescope.

ESPRESSO has achieved first light on ESO’s Very Large Telescope at the Paranal Observatory in northern Chile. This new, third-generation echelle spectrograph is the successor to ESO’s hugely successful HARPS at the La Silla Observatory. HARPS can attain a precision of around one metre per second in velocity measurements, whereas ESPRESSO aims to achieve a precision of just a few centimetres per second, due to advances in technology and its placement on a much bigger telescope.

The lead scientist for ESPRESSO, Francesco Pepe from the University of Geneva in Switzerland, explains its significance: “This success is the result of the work of many people over 10 years. ESPRESSO isn’t just the evolution of our previous instruments like HARPS, but it will be transformational, with its higher resolution and higher precision. And unlike earlier instruments it can exploit the VLT’s full collecting power—it can be used with all four of the VLT Unit Telescopes at the same time to simulate a 16-metre . ESPRESSO will be unsurpassed for at least a decade—now I am just impatient to find our first rocky planet!”

Closest Earth Match yet out of 4000 sighted exoplanets

July 24, 2015

A reminder, this is just one out of billions here in our local galaxy.

There are millions of these Earth like matches in the Milky Way.
