The galaxy is called NGC 1332 and is located in the direction of the southern constellation Eridanus. To measure […]
Astronomers Observe Exoplanet Temperatures Swinging Wildly
For the first time ever, scientists in the United Kingdom detected temperature fluctuations on a super-Earth exoplanet – 55 Cancri e, the so-called “diamond planet.” Using NASA’s Spitzer Space Telescope to study the rocky exoplanet’s thermal radiation over a two-year period, researchers led by the University of Cambridge found that the temperature on the side […]
