A 500-Billion-Year Spin: The Tiny Cosmic Twist That Could Rewrite the Universe
A faint cosmic spin – one rotation per 500 billion years – could resolve the stubborn Hubble tension by tweaking standard expansion models. Researchers led by István Szapudi showed this tiny rotation harmonizes supernova and cosmic microwave…

Strongest Evidence of Alien Life Yet Found 124 Light-Years Away : ScienceAlert
Astronomers announced Thursday that they had detected the most promising “hints” of potential life on a planet beyond our Solar System, though other scientists expressed scepticism.
There has been vigorous debate in scientific circles about…

Runaway Star Might Explain Fast Radio Bursts
Highly magnetic neutron star is wandering our Milky Way galaxy. Astronomers using NASA’s Hubble Space Telescope have tracked a rare and fast-moving magnetar – called SGR 0501+4516 – as it speeds through the Milky Way. Its origin remains…

Feasibility study of multi Laue lens based SPECT with a dedicated 3D reconstruction algorithm using Monte Carlo simulations
This section describes the methods used to model and characterize the design of the proposed multi-lens-based SPECT system, shown in Fig. 1a. To model and study the envisioned system behaviour, we developed two different studies in Mathematica27…

A galactic pearl in a distorted shell
This recent JWST image shows a galaxy-scale strong lensing system, consisting of a distant spiral galaxy that is being lensed by a bright, massive elliptical galaxy in the galaxy cluster SMACSJ0028.2-7537. This combined image is composed of four…

The low-frequency cosmic microwave background
The Planck satellite’s highly precise measurements of the temperature and polarization properties of the cosmic microwave background (CMB) have provided detailed information about the cosmological model, but other features of the CMB remain…
