Simulations show that jets that form in the solar chromosphere are projected farther outward when the coronal temperature is lower. They’re shorter when the coronal temperature is higher.

Results from the ExploreNEOs program suggest that roughly 100 near-Earth asteroids with diameters of 1 km or more are actually dormant short-period comets (i.e., asteroidal objects of cometary origin).

A clear correlation is found between black-hole mass and host galaxy total stellar mass using 262 broad-line AGN in the nearby universe — useful for cases when the stellar bulge can’t be resolved.

Emission from SGR J1745-2900, the magnetar at the galactic center, may have been due to the interaction between the shock generated by its X-ray outburst, and the ionized gas cloud G2.

The properties of the ultra-compact dwarf galaxy M59-UCD3 in the nearby Virgo Cluster suggest that it may represent an extreme population of tidally stripped galaxies.

Gaps observed in NIR images of protoplanetary disks could be due to dust evolution rather than the presence of planets. Longer-wavelength observations can differentiate between the two mechanisms.
