The Heavens Declare the Glory of God
Psalm 19:1-4: The heavens declare the glory of God; and the firmament sheweth his handiwork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard. Their line is gone out through all the earth, and their words to the end of the world.
New comet discovered
Update: Comet Atlas appears to be breaking apart. Astronomers at the University of Maryland and Caltech have used the Ningbo Education Xinjiang Telescope to get a false color image showing an elongation of the nucleus. The brightness forecasts will be downgraded if this is indeed happening.
Comet C/2019 Y4 (ATLAS) was discovered on December 28, 2019, making it the last comet discovered in 2019. It has been brightening faster than expected. It's possible the comet will give us a long overdue naked eye view in the night sky sometime in April or May when it gets closer to the Sun. Comets are notoriously unpredictable though. There's a chance that its current rapid increase in brightness may be caused by the comet breaking apart . In that case, it won't put on a good show later when it approaches the Sun. You can find the comet on a sky atlas here
