An article published in the journal “The Astrophysical Journal” reports the analysis that led to unveil the origin of two gas flows from the newborn star MMS5/OMC-3. A team of researchers used the ALMA radio telescope to study this situation which was a mystery because there are two very different flows since one is a slow outflow while the other is a fast jet and they concluded that they were formed independently in different parts of the gas disk surrounding the star.
ESA has published some images of an ancient system of trenches and river valleys near a large crater with a diameter of over 450 kilometers north of the great Hellas Planitia basin on the planet Mars obtained thanks to the Mars Express space probe’s High Resolution Stereo Camera (HRSC). The signs of water flow are mixed with the craters caused by impacts occurred between 3.5 and 4 billion years ago in that area of the Martian southern hemisphere showing the different processes that were taking place when the red planet was young and much more similar to the Earth.
NASA and The Johns Hopkins University Applied Physics Laboratory have published some photos of the Kuiper belt object cataloged as 2014 MU69 and nicknamed Ultima Thule taken by the New Horizons space probe’s LORRI camera only six minutes before its maximum approach. At only 6,628 kilometers (4,109 miles) from it and at its very high speed there was the risk of not being able to perfectly aim at a such a small object but the operation was successful.
A few hours ago a Falcon 9 rocket blasted off from the Cape Canaveral base with the telecommunications satellite PSN 6 and as secondary payloads the S5 military satellite and SpaceIL’s Beresheet Moon lander. After almost 35 minutes, Beresheet separated from the rocket’s last stage of the rocket to begin the series of maneuvers that will slowly extend its orbit to bring it to the area of influence of the Moon, where it’s to land around April 11.
A few hours ago, the Japanese space probe Hayabusa 2 touched down on the soil of asteroid Ryugu to collect some samples of regolith, the soil’s surface layer, which will be transported back to Earth. This is the first of the three possible attempts and now the Japanese space agency JAXA will have to assess whether to look for another area on the asteroid and proceed with a second attempt.
