Searching for Earth-like worlds with a fine-toothed (Astro)comb
A combination of infrared spectrograph and laser frequency comb provides unprecedented precisions in the hunt for habitable planets around nearby, cool stars.
Astrobites at AAS 233: Day 3
We report on Day 3 of the winter AAS meeting in Seattle, WA. Highlights include updates in X-ray astronomy, the discovery of a second repeating FRB, an exploration of astrochemistry in planet-forming disks, and a look at the 2020 Astronomy Decadal Survey.
A change in the tides
For tightly packed exoplanet systems, tidal force from other planets may be a significant factor to consider.
Astrophysical Classics: Evidence for Europa’s Subsurface Ocean
Let’s take a trip back to 1979 to check out the first signs of an ocean hidden deep beneath Europa’s icy shell.
Meet the AAS Keynote Speakers: Debra Fischer
Most of the known exoplanets resemble “hot Jupiters” because they’re bigger and easier to find. But how can we find Earth-like planets? Check out Dr. Debra Fischer’s plenary talk at #AAS232 to learn more about the “Past, Present, and Future” of exoplanet science.
An EPIC view of the Earth as an exoplanet
In the search for habitable exoplanets, the authors of today’s paper turn their gaze to our own planet, and what we can learn from NASA’s DSCOVR:EPIC observations of Earth.
