Dust! It’s not just collecting on your shelf, it is the topic for the last press conference at the 240th AAS.
The connection between disks and planet formation continues to expand as astronomers view them in new detail.
Screwball giant planets and ravenous stars kick off this week’s gathering of professional astronomers.
I can’t help imagining brown dwarfs as having an identity crisis. And two announcements today did not help them.
A fluorescing galaxy provides a technique for understanding the stunted growth of the smallest galaxies.
Schematic representation of rotating disc galaxies in the early Universe (right) and the present day (left). Observations with ESO's Very Large Telescope suggest that such massive star-forming disc galaxies in the early Universe were less influenced by dark matter (shown in red), as it was less concentrated.
Galaxies far, far away have less dark matter than galaxies nearby…
Einstein’s birthday present from Italy—laser gyros! (No pita needed.)
Martian meteorites could suggest that the Red Planet has an even wetter history than previously thought.
Astronomers discover the most distant dusty galaxy ever observed.
Volcanoes have the potential to make distant exoplanets potentially habitable.
NASAs upcoming Europa mission has cleared an important hurdle.
Hydrocode simulation of an impact of a Venus-sized rock/iron planet colliding with a six Earth-mass planet. The collision creates a disk of rock fragments, liquid, and vapor massive enough to create a moon of 0.1 Earth masses, large enough to be detected by Kepler. Colors indicate the density of material, with solids depicted by orange/red hues, and liquid/vapor depicted by green/blue hues.
Could exomoons be large enough for Kepler to detect?
