It’s been a busy few weeks on Mars, with the InSight Lander arriving in late November, making it the newest member of the Martian robotic ground team. The science hasn’t started yet, but the first photos of the landing area have come back, and testing of the science instruments has begun, with the first big reveal coming late last week – the first recording of Martian wind. Landed Martian robots can be found all over Mars. Note that most are no longer operational. Credit: NASA InSight provided the first landing on Mars since Curiosity in 2013. It went through the...
It wasn’t long after the discovery of exo-solar planets that scientists sent up spacecraft to look for them. The Kepler Space Telescope (KST) was NASA’s first planet finder, which has been exceeding expectations since 2009. It likely won’t get to continue on that road, as it is nearing the end of it’s life. At the same time, the Transiting Exoplanet Survey Satellite (TESS) is just starting to open it’s eyes. Today we say goodbye to one great planet hunter and hello to another. KST is part of NASA’s early 2000s spacecraft approvals that saw relatively inexpensive missions pushed forward...
Not just the title of an excellent Futurama episode, but now a real place. A planet has been found orbiting in a triple star system, a surprising find that may be more common than once thought. Astronomers from the University of Arizona used the European Southern Observatory (ESO)’s Very Large Telescope (VLT) in Chile to directly image the new planet as it orbits the brightest star in a triple system 320 light years away, in the constellation Centaurus. Orbits like this are thought to be extremely unstable due to the varying gravitational field in the system. “HD 131399Ab is one of the few exoplanets that...
