Johns Hopkins University (JHU) continues to pad its space community résumé with their interactive map, “The map of the observable Universe”, that takes viewers on a 13.7-billion-year-old tour of the cosmos from the present to the moments after the Big Bang. While JHU is responsible for creating the site, additional contributions were made by NASA, the European Space Agency, the National Science Foundation, and the Sloan Foundation.

The Soyuz-Fregat launcher will also deliver the Italian space agency’s Cosmo-SkyMed Second Generation satellite, and three CubeSats – including ESA’s OPS-SAT – into space today. CHEOPS is ESA’s first mission dedicated to the study of extrasolar planets, or exoplanets. It will observe bright stars that are already known to host planets, measuring minuscule brightness changes due to the planet’s transit across the star’s disc. Credit: ESA – S. Corvaja.

The Characterising Exoplanet Satellite, Cheops, has successfully completed its final testing phase at Airbus Defence and Space Spain, Madrid. The satellite has also passed a very important review that determined it is ready to fly. Cheops will be stored in Madrid for a few months before being shipped to the launch site in Kourou, French Guiana; launch is scheduled in the time slot between 15 October and 14 November 2019. Cheops is our first mission to focus on exoplanets, or planets beyond our Solar System, orbiting stars other than the Sun. It will make observations of stars the are known to host exoplanets to measure small changes in their brightness due to the transit of the planet across the star's disc. Cheops will target in particular stars hosting planets in the Earth-to-Neptune size range. The information will enable precise measurements of the sizes of the orbiting planets to be made: combined with measurements of the planet masses, this will provide an estimate of their mean density – a first step to characterising planets outside our Solar System. Cheops paves the way for the next generation of our exoplanet satellites, with two further missions – Plato and Ariel – planned for the next decade to tackle different aspects of the evolving field of exoplanet science. The mission is a partnership between us and Switzerland with additional contributions from Austria, Belgium, France, Germany, Hungary, Italy, Portugal, Spain, Sweden, and the United Kingdom. This film contains contributions from Nicola Rando, Cheops Project Manager, ESA; and Kate Isaak, Cheops Project Scientist, ESA.

A team of researchers led by University of Chicago astronomer Rafael Luque analyzed data acquired by both NASA’s Transiting Exoplanet Survey Satellite (TESS) and ESA’s CHaracterising ExOPlanet Satellite (Cheops) and found a unique planetary system. Orbiting a star cataloged as HD110067, this system contains six sub-Neptune planets. Incredibly, all six planets are orbiting in direct resonance with each other. The results of the work were published on November 29 in Nature.
Working through the calculations to find potential resonances, the team matched one set of transits to a planet orbiting in 31 days. Again, the orbit was a 3/2 resonance, with planet d orbiting three times to planet e’s two times. However, there were possibly two more unmatched transits in the data. TESS had only observed each one a single time, making confirmation difficult. One planet orbited in 41 days; the other in 55. Credit:ESA
The animation shows the orbits of the six planets discovered transiting the bright K-dwarf star HD110067. The six planets were found from a combination of NASA/TESS and ESA/CHEOPS observations. They have sizes between Earth and Neptune, although they are very likely a mix of hydrogen gas, water and rock. All six planets orbit in a so-called resonant chain - this synchronised dance means the ratio of planet orbits form perfect fractions - in this case 3/2 and 4/3. Resonances lend themselves perfectly to music, and the notes played as each planet passes across (or transits) its star are each tied to the orbital frequency of the orbit. In reality the six planets play a G7sus4 chord with a base note of F-24 (1.27microHz). The background image is from raw data from NASA's Transiting Exoplanet Survey Satellite (TESS; processed by Ethan Kruse). Animations, annotations and sound composition all made by Dr Hugh Osborn. For clarity the planets have been scaled up relative to their star, and the orbits have been precisely set to the nearest resonant orbit (while in reality they are ~0.1% away). Annotations describe the global effort to solve this mysterious system, including observations from NASA TESS, ESA CHEOPS, radial velocities from HARPS-N & Carmenes, and ground-based photometry from NGTS, Saint-Ex, Tierras, LCO and MuSCAT telescopes. The paper, "A resonant sextuplet of sub-Neptunes around the bright star HD 110067" by Luque, Osborn, Leleu, Pallé et al is released on 30/11/2023 The results of the work were published on November 29 in Nature.
