Life on Earth or Mars could have been brought to the moons of Jupiter or Saturn on rocks blasted off those planets, researchers say.
We review the state of the field of terrestrial planet formation with the goal of understanding the formation of the inner Solar System and low-mass exoplanets.
Earth's volatile elements (H, C, and N) are essential to maintaining habitable conditions for metazoans and simpler life forms.
Habitable Zones & Global Climate
The habitable zone (HZ) around a star is typically defined as the region where a rocky planet can maintain liquid water on its surface.
Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry.
We present the results of simulations on the detectability of O2 in the atmosphere of Earth twins around nearby low mass stars using high resolution transmission spectroscopy.
We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument.
We study the masses and radii of 60 exoplanets smaller than 4 Earth radii with orbital periods shorter than 100 days.
Context: The dusty debris disk around the ~20 Myr old main-sequence A-star beta Pic is known to contain gas.
"We stand on a great threshold in the human history of space exploration."
"For thousands of years, humans have looked up at the stars and wondered whether life exists beyond our home planet."
