Gamma-ray bursts (GRBs) are produced by rare types of massive stellar explosion. Their rapidly fading afterglows are often bright enough at optical wavelengths...
Heavy-element production in a compact object merger observed by JWST
The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the...
Highly porous nature of a primitive asteroid revealed by thermal imaging
Carbonaceous (C-type) asteroids 1 are relics of the early Solar System that have preserved primitive materials since their formation approximately 4.6 billion...
Identification of carbon dioxide in an exoplanet atmosphere
Carbon dioxide (CO2) is a key chemical species that is found in a wide range of planetary atmospheres. In the context of exoplanets, CO2 is an indicator of the...

The paper confirms the report of Kulkarni et al. (1979) who discovered IR bursts from the X-ray rapid burster, MXB1730-335. Two bursts at 2.2 microns, each of...
A PHASE-MODULATED Michelson interferometer1 and a helium cooled Rollin2 photoconductive far infrared detector, at the focus of a 35 cm aperture Cassegrain...
Minutes-duration optical flares with supernova luminosities
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days 1. Their short observed duration implies a...
