In a press briefing that included a number of scientists working on NASA’s New Horizons mission, the first discoveries on the Kuiper Belt object cataloged as 2014 MU69 and nicknamed Ultima Thule were presented, obtained thanks to data received during the January 1, 2019 flyby. They’re based on information that’s still incomplete, which could be contradicted by high resolution photos and other data but for the moment this object doesn’t appear to have neither moons nor rings, or at least not of relevant sizes, no impact craters were found on its surface nor were traces of atmosphere.
NASA published the first detailed images of the Kuiper Belt object cataloged as 2014 MU69 and nicknamed Ultima Thule. Captured by the New Horizons space probe’s LORRI and MVIC instruments approximately 90 to 30 minutes before its closest approach, they finally clearly show this object’s double-lobe structure. In jargon, it’s called a contact binary and is the result of two close objects that collide at low speed and end up merging. The larger lobe has been nicknamed Ultima and the smaller Thule.
NASA has confirmed that its New Horizons space probe has successfully flew by the Kuiper Belt object cataloged as 2014 MU69 and nicknamed Ultima Thule. After completing its second mission, New Horizons turned to Earth, communicated a series of telemetric data that allowed to confirm that it’s in good health and started sending the data it collected.
NASA’s New Horizons spacecraft has just completed its flyby of the object known as 2014 MU69 and nicknamed Ultima Thule. The automatic program to proceed with the photos and the other detections of its target was activated a few days ago so, after sending the last images taken when it was still almost two million kilometers away, New Horizons aimed its instruments at Ultima Thule. If all went well, in the next few hours it will communicate it to the mission control center and start sending the data it collected, a process that will continue for an estimated time in about 20 months.
Various telescopes such as the Hubble Space Telescope, the SOFIA flying telescope and the ALMA radio telescope were used to examine the innermost region of Comet 46P/Wirtanen, nicknamed the Christmas comet because in recent days it made an Earth flyby. This expression has to be considered in a broad sense since it reached 11.6 million kilometers (more than 7 million miles) on December 16. This was enough to obtain interesting information such as the detection of hydrogen cyanide molecules in its nucleus by ALMA.
