A team of astronomers from Maryland, Hawaiʻi, Israel and France has produced the most detailed map ever of the orbits of galaxies in our extended local neighborhood, showing the past motions of almost 1,400 galaxies within 100 million light years of the Milky Way. The team, including co-author Brent Tully of the Institute for Astronomy at the University of Hawaiʻi, reconstructed the galaxies’ motions from 13 …

In October, astronomers at the University of Hawaiʻi at Mānoa Institute for Astronomy (IfA) made a stunning discovery with the Pan-STARRS1 telescope—the first interstellar object seen passing through our Solar System. Now, an international team lead by IfA Astronomer Karen Meech has made detailed measurements of the visitor’s properties. “This thing is very strange,” said Meech. Originally denoted A/2017 U1 (with the A for “asteroid”), the body is now …

Small asteroid or comet ‘visits’ from beyond the solar system

Diagram of our solar system shows the dramatic path of A/2017 U1

A small, recently discovered asteroid—or perhaps a comet—appears to have originated from outside the solar system, coming from somewhere else in our galaxy. If so, it would be the first “interstellar object” to be observed and confirmed by astronomers. This unusual object—for now designated A/2017 U1—is less than a quarter-mile (400 meters) in diameter and is moving remarkably fast. Astronomers …

Documenting the last permafrost in Hawaiʻi

Mauna Kea

In the coldest climate, on the tallest summits of Hawaiʻi, temperatures fall below freezing during winter nights. In 1969 Alfred Woodcock discovered areas inside cinder cones on Maunakea that are permanently frozen. At one place the ice was about 32 feet thick and 27 yard long, buried beneath about one foot of boulders, the only permanent ice known in all of …

UH part of astronomical discovery that changes understanding of universe

A binary neutron star merger and resulting kilonova explosion.

University of Hawaiʻi researchers played a major role in one of the most significant astronomical discoveries in decades—the first observations of a binary neutron star merger and resulting kilonova explosion. The discovery fundamentally affects our understanding of the origin of many of the elements common on Earth and in our bodies. UH astronomers, together with their international collaborators, announced the discovery in articles …

Local students get an Akamai experience at telescopes on Hawaiʻi Island and Maui

Akamai interns around podium

Students from the University of Hawaiʻi System were among the 29 participants in the 2017 Akamai Internship Program that gives college students from Hawaiʻi an opportunity to gain a summer work experience at an observatory, company or scientific/technical facility in Hawaiʻi. The students spent the eight-week program working on research projects with mentors at a variety of STEM facilities on HawaiʻiIsland and Maui including the telescopes on Maunakea and Haleakalā. …

Hawaiʻi students expand research and astronomy skills

Students and staff of the 2017 HI STAR program

Twenty middle and high school students from Oʻahu, Maui, Molokaʻi and Hawaiʻi Island learned core astronomy and research skills at this year’s HI STAR program. HI STAR, the Hawaiʻi  Student Teacher Astronomical Research program, is a week-long summer astronomy program held at the University of Hawaiʻi at Mānoa for students entering grades 8–11. This was the 11th year of the program. Students gain an in-depth understanding of astronomy throughout the week of intense HI …

Astronomers discover variability in the Seven Sisters of the Pleiades Cluster

The brightest members of the Pleiades cluster form a spectacular group of naked-eye stars that have played a central role in cultures around the world for millennia. Native Hawaiians used the Makaliʻi to mark the beginning of the new year and the beginning of “tax collecting season,” while the “Seven Sisters” feature prominently in ancient Greek mythology. But not everything is known …
