This is not likely made up by the presence of numerous black holes or more exotic objects in the plane since, for instance, the stability of the solar system is such as to preclude the numerous encounters with such gravitational objects in its lifetime. It appears that there must be a ...
The Milky Way is the galaxy that contains our Solar System. This name derives from its appearance as a dim "milky" glowing band arching across the night sky, in which the naked eye cannot distinguish individual stars. The term "Milky Way" is a translatio
galaxiesthrough time,starformation, and our own Solar System, are still just the beginning. Recently, scientists from all over the world converged – virtually – to apply for observation time with Webb during its fourth year of science operations, which begins in July 2025....
We use NIRCam and NIRISS imaging to study the resolved Firefly Sparkle and explore the stellar mass distribution in the clusters versus the diffuse arc. Photometry, derived by joint modelling of the 10 clusters and the diffuse arc using GALFIT10, shows that nine clusters are unresolved, even i...

We could have a lively and intellectually stimulating debate on the merits of games versus applications. Simply, the differences between games and apps are as follows: If a person likes a game, he or she tends to play it for a while, maybe for a few weeks or even months, and then ...
Spectra are plotted as intensity (TA*), in mK, versusVLSR, in kilometres per second. The top two panels show theJ = 2 → 1 andJ = 3 → 2 transitions of PN, followed by the four hyperfine/lambda-doubling components of theJ = 2.5 → 1.5 transition of PO...

General Observer time with Webb is more competitive than ever. Arecord-breaking 2,377 proposalswere submitted by the Oct. 15, 2024 deadline, requesting about 78,000 hours of observation time. This is an oversubscription rate, the ratio defining the observation hours requested versus the actual ...
