Sizes of Black Holes Throughout the Universe
Can black holes of any mass exist, or are there gaps in their possible sizes? Mergers may play a large role in the answer to this question.
Finding A Planet Through the Dust
Finding planets in the dusty and crowded galactic center is a difficult task! A new study demonstrates the use of infrared microlensing surveys for discovering exoplanets.
New Target for an Old Method: Hubble Measures Globular Cluster Parallax
For the first time, the distance to a metal-poor globular cluster is determined using high-precision parallax measurements.
When Supermassive Black Holes Wander
Are supermassive black holes found only at the centers of galaxies? A new study suggests not — and there may be a number of them wandering through our galaxy unseen.
Where Should We Look for Life?
A recent study explores whether Sun-like stars or low-mass M dwarfs are the best target as we search for exoplanets with detectable signatures of life.
Heating the Chromosphere in the Quiet Sun
Could constant, tiny magnetic-field hiccups be responsible for heating the upper atmosphere of the Sun?
Capturing Neutrinos from a Star’s Final Hours
What happens in the late stages of stellar evolution? Neutrinos — the elusive messengers of nuclear fusion in stellar interiors — might hold the answer.
Peering Into an Early Galaxy
ALMA has provided a detailed look into the interior of CR7, one of the most distant, early galaxies known.
First Hours of the GW170817 Kilonova: Why So Blue?
A recent study explores the source of the early blue emission we observed when two neutron stars merged in August 2017.
