Recent research also reinforces the finding that the happenings in star clusters and their respective galaxies are very similar.

Status: Accepted to Astronomical Journal. Open access on arXiv
This article states the potential for small planets to form around dwarf stars. Scientists believe that this potential is likely related to the star’s metallicity.
The forward strides in the planet formation theory have allowed for a type of…
Paper Title: HABITABLE ZONES IN BINARY STAR SYSTEMS: A ZOOLOGY
First Author’s Institution: Rubin Observatory / Department of Astronomy, University of Washington, Seattle, 98015 WA, USA firstname.lastname@example.org
Status: Published in MDPI Galaxies. Open access on arXiv.
If you’re trying to look for another planet in the habitable zone of a star, this overview will be quite useful to you. A traditional habitable zone is defined as a region where the temperature is enough so that liquid water can exist near the surface of the planet, and therefore, possibly support life. When considering habitable…

Astronomers have recently detected a new exoplanet nearly 13,100 light-years from Earth, but how did they find it and…
If you’ve been through a storm, you may have gotten your power knocked out at one point or another. However, how often have you seen total power failure for a major part of a continent? Maybe once in a lifetime, such as the 1989 Quebec power outage.
The culprit of many of these widespread electricity flaws is none other than the same thing that allows life to thrive on Earth — the sun.
The sun is capable of putting out huge ejections of plasma into space, and some of these streams incidentally are detected on Earth. …
The space sciences are arguably the most underrated out of all areas of science in many cases. This is quite surprising since many children are fascinated and inspired by things “out of this world”, from mysterious black holes to the other worlds in our solar system.
The United States Astronomy and Astrophysics Competition Foundation seeks to motivate those high school students interested in Astronomy and Astrophysics by hosting competitions and encouraging the study of the contents presented in the IOAA syllabus. The Foundation gives students an opportunity to compete in a first-round competition, then those who pass the first round…
The IOAA International Board is organising Global e-Competition on Astronomy and Astrophysics (GeCAA) as an alternate educational event for the benefit of students who were due to participate in IOAA this year.
The event will be held in 2 categories, individual and group.
Individual category will have one test based on theoretical problems, one on the data analysis problems, one on observation related problems. The rounds for this category will be held on September 25, 26 and 27, 2020.
In group category, the participants will be grouped in mixed
international teams by the organisers and will be given a set of…
Hello, we are the USAAAO! We advance and promote astronomy and astrophysics education through competition and aim to spread interest in the space sciences.
