For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and âweighedâ a galaxy, in the early Universe, that has a mass that is similar to what our Milky Way galaxyâs mass might have been at the same stage of development. Found at around 600 million years after the Big Bang, this lightweight galaxy, nicknamed the Firefly Sparkle, is gleaming with star clusters â 10 in total â that researchers examined in great detail. Other galaxies Webb has detected at this period in the history of the Universe are significantly more massive.

Video: 00:09:01 Proba-3Â is such an ambitious mission that it needs more than one single spacecraft to succeed. In order for Proba-3âs Coronagraph spacecraft to observe the Sunâs faint surrounding atmosphere, its disk-bearing Occulter spacecraft must block out the fiery solar disk. This means Proba-3âs Occulter ends up facing the Sun continuously, making it a valuable platform for science in its own right.
Proba-3 is scheduled for launch on a PSLV-XL rocket from Satish Dhawan Space Centre in Sriharikota, India, on Wednesday, 4 December, at 11:38 CET (10:38 GMT, 16:08 local time).

NASA/JPL-Caltech This Oct. 4, 2017, illustration shows a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajianâs Star or Tabbyâs Star. The star has experienced unusual dips in brightness over a matter of days, as well as much subtler but longer-term dimming trends. Scientists proposed several explanations for this unexpected behavior, ranging from Tabbyâs Star swallowing a planet to alien âmegastructuresâ harvesting the starâs energy. However, a study using NASAâs Spitzer and Swift missions as well as the Belgian AstroLAB IRIS observatory suggests that the cause of the dimming over long periods is likely an uneven dust cloud moving around the star.
Learn more about this enigmatic star, named after Tabetha Boyajian, the Yale University postdoc who discovered it with the help of citizen scientists.
