NASA’s Spitzer space telescope captured a new image of the so-called Christmas Tree Cluster, so nicknamed for its shape. That appearance is enhanced by a remarkable star formation with the consequent presence of protostars that emit a light that appears pink or red to Spitzer that gives the area an effect similar to the Christmas tree’s balls. It’s part of a set of objects collectively known as NGC 2264 which also includes the Snowflake Cluster, the Cone Nebula and the Fox Fur Nebula.

The "cotton candy exoplanets" of the Kepler 51 system studied with the Hubble Space Telescope

An article to be published in “The Astronomical Journal” reports a study on three gas exoplanets discovered in the Kepler 51 system belonging to a rare type that has a very low density even by the standards of these planets. A team of researchers led by Jessica Libby-Roberts, a graduate student at the University of Colorado, Boulder, used the Hubble Space Telescope to study those three exoplanets confirming their density so low as to deserve nicknames such as “cotton candy planets” or “super puffs”. This study suggests that they’re quickly losing mass so in the distant future they could turn into mini-Neptunes, a much more common category.

A little while ago Boeing’s CST-100 Starliner spacecraft landed at the White Sands Missile Range in New Mexico, ending its Boe-OFT (Boeing Orbital Flight Test) mission. Unlike the previous American spacecraft, this one doesn’t splash down in the ocean but lands on the ground. The ground staff intervened in an exercise of the assistance activity that will take place in manned missions.

A little while ago, Boeing’s CST-100 Starliner spacecraft blasted off atop a ULA Atlas V rocket from the Cape Canaveral base in its Boe-OFT (Boeing Orbital Flight Test) mission. After about 15 minutes it successfully separated from the rocket’s last stage. After a little more than half an hour the first of a series of maneuvers for orbit insertion was schduled but a problem emerged that required that the possible options to be assessed to have the CST-100 Starliner go for a proper orbit insertion and on its way to carry out its mission. Boeing has control of the spacecraft, which is in a stable orbit, so it’s not in danger.

A few hours ago a Soyuz rocket was launched from the Kourou base, in French Guiana. After about 23 minutes the Cosmo-SkyMed Second Generation satellite successfully separated from the rocket’s Fregat last stage. About 85 minutes after the launch, the CHEOPS space telescope successfully separated from the rocket’s Fregat last stage.

The COSMO-SkyMed Second Generation satellite is the first of a constellation of two satellites that aims to replace the first generation’s four satellites. It’s a system of radar satellites for the territory observation, the result of a collaboration between the Italian Space Agency and the Italian Ministry of Defense.

The purpose of ESA’s CHEOPS (Characterizing ExOPlanets Satellite) space telescope is to conduct follow-up study of exoplanets using the transit method, which means observing the ones that pass in front of their star.
