The presence of green spaces near homes and schools is strongly associated with improved physical activity and mental health outcomes in kids, according to a massive review of data from nearly 300 studies.

2.    Investigating The Potential for Life Around the Galaxy’s Smallest Stars

When the world’s most powerful telescope launches into space this year, scientists will learn whether Earth-sized planets in our ‘solar neighborhood’ have a key prerequisite for life — an atmosphere. These planets orbit an M-dwarf, the smallest and most common type of star in the galaxy. Scientists do not currently know how common it is for Earth-like planets around this type of star to have characteristics that would make them habitable.

3.    ‘Planet Confusion’ Could Slow Earth-Like Exoplanet Exploration

By using Earth’s own solar system as a model of an unexplored star system, researchers calculated that even with direct-imaging techniques and the increased capabilities of future, high-powered telescopes, exoplanets as different as Uranus and Earth could be mistaken for one another.

4.    Earth Is Dimming Due to Climate Change

Warming ocean waters have caused a drop in the brightness of the Earth, according to a new study. Researchers used decades of measurements of earthshine — the light reflected from Earth that illuminates the surface of the Moon — as well as satellite measurements to find that there has been a significant drop in Earth’s reflectance, or albedo, over the past two decades.

5.    Mysterious Metal-Rich Near-Earth Asteroids

1 Oct 2021

New research investigated two metal-rich asteroids in our own cosmic backyard to learn more about their origins, compositions, and relationships with meteorites found on Earth. These metal-rich NEAs were thought to be created when the cores of developing planets were catastrophically destroyed early in the solar system’s history, but little more is known about them.

6.    Astronomers May Have Discovered the First Planet to Orbit 3 Stars

1 Oct 2021

In a distant star system — a mere 1,300 light-years away from Earth — UNLV researchers may have identified the first known planet to orbit three stars. Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed the novel phenomenon, consist of two or more stars that are gravitationally bound to each other.
