A coherent story of the Universe from galaxy and CMB surveys

January 31, 2023

Combining data from the Dark Energy Survey and the South Pole Telescope, scientists piece together a coherent story of the Universe from galaxy and CMB surveys. These are some of the most stringent tests of the standard cosmological model using cross-correlations of independent data sets.


“NASA’s TESS Discovers Planetary System’s Second Earth-Size World”, www.nasa.gov

January 11, 2023

Using data from NASA’s Transiting Exoplanet Survey Satellite, scientists have identified an Earth-size world, called TOI 700 e, orbiting within the habitable zone of its star – the range of distances where liquid water could occur on a planet’s surface. The world is 95% Earth’s size and likely rocky.
