Tonight ...Big Dipper stars point to North Star 🌌🌟

The 2 outermost stars in the bowl of the Big Dipper always point to the North Star, aka Polaris. That's why astronomers call these stars The Pointers. Read more: https://t.co/jPAsEQyM2P 👓

How big is the solar system? If you shrunk the Sun to the size of a dime on the goal line of a football field, Earth would be on the two-yard line…and Pluto would be almost 80 yards away. More: https://t.co/HSzDzeQlT4 #SuperBowl

Fans in Manila have painted a
tribute mural to Kobe Bryant
and his daughter Gianna at
the famed court in Taguig.

“It’s the one thing you can
control. You are responsible
for how people remember
you... or don’t. So don’t
take it lightly.”

Look east before sunrise Wednesday. The lit side of the waning moon will point to Jupiter, which is very bright, but very near the sunrise glare. Notice that the lighted portion of the waning moon will be pointing to it!

When is the next Blue Moon? 🌔

According to folklore, the next Blue Moon will come on October 31, 2020. It'll be called a Blue Moon because it'll be the 2nd of 2 full moons in a single calendar month. Read more: https://t.co/66sByHOMXZ 👓

Overnight January 4 / 5 - Earth at Perihelion - The closest distance to the Sun in our annual elliptical (oval-shaped) orbit.

If you see astrophysicists dancing in the streets, this could be why.

No need to panic, but the red supergiant star Betelgeuse (yes there is a star with that name), one of the brightest in the nighttime sky, marking the left armpit of the constellation Orion, is mysteriously dimming, having lost 60% of its brightness across the past six months.

Like Earth's orbit around the sun, the moon's orbit isn't a perfect circle. The moon will swing to its farthest from Earth for 2020 on March 24, and then comes closest to Earth about 2 weeks later, on April 7. 🌕 Read more: https://t.co/rwhmMmVsW3 👓

“Twenty years from now you
will be more disappointed by
the things you didn’t do than
by the ones you did. So throw
off the bowlines. Sail away
from the safe harbor. Catch
the trade winds in your sails.
Explore. Dream. Discover...”

Here's something to see on a 1st quarter moon...

Tim Yacyshyn in Richmond, BC, Canada captured it Oct 5. He wrote: "Taken exactly 12 hours after 1st quarter. As you can see, the famous Lunar X stands out quite prominently." Thanks, Tim!
