We only recently determined that planets do in fact exist around other stars. The discovery of such “exoplanets” is of interest not just to science…View More How are exoplanets portrayed in science fiction?
Astrobiology studies the origin, evolution, and possible distribution of life in the universe. One important aspect of astrobiology is the search for biosignatures and bioindicators.…View More Why might argon be an indicator of extraterrestrial life?
Cubesats are becoming more common. In low Earth orbit, they are becoming so prevalent that concerns are arising about space debris and interference with Earth-based…View More How are cubesats advancing astrophysics?
A booming area of space science is the study of “exoplanets”, the term for planets outside our Solar System. Telescopes like the Transiting Exoplanet Survey…View More White dwarfs’ exoplanets – what do we know about them?
Mercury, one of Earth’s rocky neighbors, is one of our Solar System’s most enigmatic planets. It is notoriously difficult to study due to its close…View More How did MESSENGER revolutionize our understanding of Mercury?
The TRAPPIST-1 system is notable for having Earth-like planets that may be habitable. They are rocky and in the so-called “habitable zone” where water may…View More What do we know about the TRAPPIST-1 system’s habitability?
Stars are dynamic entities. They emit radiation and charged particles that affect the planets that orbit them. This “space weather” is thus an important factor…View More How does stars’ radioactivity affect the habitability of nearby planets?
Astrobiology is a relatively recent area of study that investigates the origin and evolution of life in the universe. Being an astrobiologist combines perspectives from…View More What’s it like working as an astrobiologist?
Recently, an interstellar object named ‘Oumuamua entered our solar system. It was the first such observed object in recorded history. Scientists were thus already watching…View More Mainstreaming SETI: ‘Oumuamua and Light-sails
Art that depicts space drives us to explore it. Well before astronauts left Earth, the work of the “father of modern space art” Chesley Bonestell…View More The work of space artists: visualizing the cosmos
