In 1963, astronomer Maarten Schmidt had a sudden revelation that quasars are exceedingly distant and unimaginably luminous. His insight changed our notion of what the universe is like.

Astronomers studying a globular star cluster accidentally discovered a more-distant galaxy behind it. The little galaxy is 30 million light-years away and is nicknamed Bedin 1. The videos in this post take you there.
This image, taken with Hubble’s Advanced Camera for Surveys shows a part the globular cluster NGC 6752. Behind the bright stars of the cluster a denser collection of faint stars is visible — a previously unknown dwarf spheroidal galaxy. This galaxy, nicknamed Bedin 1, is about 30 million light-years from Earth. Im https://www.spacetelescope.org/images/heic1903a/age via Hubble Space Telescope.
The 2019 Chinese New Year – which coincides with the February new moon – starts February 5 in Asia (February 4 in the west) and rings in the Year of the Pig.
A fast-moving comet, C/2018 Y1 (Iwamoto), is nearing its February encounter with the sun and Earth. It’ll pass near some galaxies as seen from Earth, providing a great opportunity for astrophotographers. Charts and more info here.

A scientist explains one of the most mind-blowing ideas in physics in under 5 minutes.
An intriguing ancient rock found on the moon and brought back by the Apollo 14 mission may actually have originated from Earth, a new study says.
This 2 gram fragment of rock is composed of quartz, feldspar, and zircon - all common on Earth but rare on the moon. Did it originate from Earth? Image via NASA.
The space rock traveled over West Palm Beach, above the Florida Keys, and then to Viñales, a town in Pinar del Río, Cuba. It left a smoke trail seen by many. Images and video here.

In February, the 2 bright planets up before the sun are Venus (brighter) and Jupiter. Saturn is there, too, if you look closely. Mars shines in the evening sky all month. Starting in mid-February, look for Mercury low in the west as dusk gives way to darkness.
View larger. | V. Srinivasagopalan caught both Venus (below) and Jupiter on September 22, 2018 from Bangalore, India. Remember, Venus is going into the sunset in October, 2018. Watch for it soon!
Groundhog Day is tied to the movement of Earth around the sun. Falling approximately midway between a solstice and an equinox, it’s the year’s 1st cross-quarter day.
