Rare Appearance of Two Comets in SOHO/LASCO C2 Field of View January 18, 2021.

It is rare to see two comets moving in the SOHO/LASCO C2 Field of View. That occurred on January 18, 2021. In this annotated image, arrows point out the two comets. The brighter object is a member of the Kreutz group of sun grazing comets. Both objects show tails extending away from the sun. BothContinue reading “Rare Appearance of Two Comets in SOHO/LASCO C2 Field of View January 18, 2021.”

At discovery on January 3, 2021, new comet C/2021 A1 (Leonard) was located in the northern constellation of Canes Venatici (CVn) and moving northward in that constellation in January 2021.For most of the year 2021, comet C/2021 A1 is expected to remain at high northern declinations. Depending on your latitude, the comet may be circumpolar,Continue reading “Comet C/2021 A1 (Leonard) Sky Path in 2021”

A Newly Discovered ATLAS Comet

A new solar system object first observed on December 28, 2020, at magnitude 18.30 o by the ATLAS Survey station T08 ATLAS-MLO, Mauna Loa was found to exhibit a coma by follow-up observations. The new comet is designated C/2020 Y2 and named for the parent survey ATLAS. At discovery, C/2020 Y2 was near 5.8 auContinue reading “A Newly Discovered ATLAS Comet”

Initial look inside Hayabusa2 sample chamber show dark black particles

Japan Aerospace Exploration Agency (JAXA) opened the sample chamber from the re-entry capsule of the asteroid explorer “Hayabusa2” on December 14, 2020, and found dark black grain particles assumed to be from asteroid (162173) Ryugu outside of the main chamber attached to the sample catcher entrance. This image was taken with a scope camera byContinue reading “Initial look inside Hayabusa2 sample chamber show dark black particles”

Goldstone Delay Doppler Radar Images of (153201) 2000 WO107 Suggest a Bi-lobate Contact Binary Object

This sequence of delay doppler radar images of (153201) 2000 WO107 in November 2020 show an object like a bowling pin, a bilobate object or contact binary rotating slowly. It completes half of a revolution between 03:37:15 UTC and 12:13:32 UTC in the top left frames or 2.6 hours. The rotational period is approximately 5.2Continue reading “Goldstone Delay Doppler Radar Images of (153201) 2000 WO107 Suggest a Bi-lobate Contact Binary Object”
