Astrobiologists are focused on resolving two central questions to understand the environmental and chemical limits of life. By understanding life's boundaries, they intend to identify possible biosignatures in exoplanet atmospheres ...
Using the Gemini-South telescope, astronomers have performed a photometric study of the lenticular galaxy NGC 4546. Results of the new research provide more clues about the structure and nature of the galaxy's globular cluster ...
The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists ...

Using ESO's Very Large Telescope (VLT) in Chile, astronomers have discovered a low-mass stellar companion embedded in the disk of the young pre-main-sequence (PMS) massive star designated MWC 297. The finding is detailed ...
Chinese astronomers have carried out spectroscopic observations of the lenticular galaxy IC 676. Results of these observations provide more insights into the nature of the galaxy's double nuclei. The study was detailed in ...
Asteroids come in all shapes and sizes, and now astronomers at MIT and elsewhere have observed an asteroid so heavily cratered that they are dubbing it the "golf ball asteroid."

A large team of space scientists working in Canada has found evidence of a fast radio burst with a steady 16-day cycle. The team has published a paper describing their findings on the arXiv preprint server.
Observations using the IRAM 30 meter telescope and the NOEMA Interferometer have unveiled the presence of molecular oxygen in Markarian 231—the nearest known quasar. The finding, detailed in a paper published on the arXiv ...
A grand synthesis of Rosetta data has shown how its target comet repeatedly changed color during the two years it was watched by the spacecraft. The chameleon comet's nucleus became progressively less red as it made its close ...
