'Bare' super-earths offer clues to evolution of hot atmospheres

A group of astronomers from the Astrobiology Center, the National Astronomical Observatory of Japan, the University of Tokyo, and other institutes, discovered two rocky super-Earth exoplanets lacking thick primordial atmospheres ...

Small amount of lithium production in classical nova

A new study of lithium production in a classical nova found a production rate of only a couple of percent that seen in other examples. This shows that there is a large diversity within classical novae and implies that nova ...

Charting the expansion history of the universe with supernovae

An international research team analyzed a database of more than 1000 supernova explosions and found that models for the expansion of the Universe best match the data when a new time dependent variation is introduced. If proven ...

Telescope photographs the next target asteroid for Hayabusa2

On December 10, 2020 (Hawai'i Standard Time), the Subaru Telescope imaged the small asteroid 1998 KY26, the target of Hayabusa2's extended mission. The positional data for 1998 KY26 collected during the observations will ...

Direct image of newly discovered brown dwarf captured

Astronomers using two Maunakea Observatories—Subaru Telescope and W. M. Keck Observatory—have discovered a key benchmark brown dwarf orbiting a sun-like star just 86 light-years from Earth that provides a key reference ...

Classifying galaxies with artificial intelligence

Astronomers have applied artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have achieved a very high accuracy for finding and classifying spiral ...

TRAPPIST-1 planetary orbits not misaligned

Astronomers using the Subaru Telescope have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the ...

The whole picture of a distant supercluster in three dimensions

Using the Subaru Telescope and Gemini-North Telescope, a team of astronomers has revealed that the supercluster CL1604, a distant supercluster located about 7.3 billion light-years away, is a large-scale 3-D structure extending ...

Oldest galaxy protocluster forms 'queen's court'

Using the Subaru, Keck and Gemini Telescopes, an international team of astronomers has discovered a collection of 12 galaxies that existed about 13.0 billion years ago. This is the earliest protocluster ever found. One of ...
