Congratulations to Jimmy Carter for Best Spoken Word at the #GRAMMYs — his THIRD! In 2015, I spoke with President Carter on @StarTalkRadio about his heroic efforts to eradicate the Guinea Worm. [Audio: 50min] https://t.co/rJxv1cWvUP

After the #GRAMMYs (or now) discover the geeky side of @katyperry. On @StarTalkRadio she and I chatted about extraterrestrials, prisms, music, curiosity, the pursuit of knowledge & more [Audio: 50min] - https://t.co/KuLacDO1Rv.

After the #GRAMMYs (or now) learn another side of @JanelleMonae. We chatted along with author @MargotShetterly during our @StarTalkRadio episode on the film “Hidden Figures.” [Audio 50min]: https://t.co/fpo0yBZ6FE

Good luck to @CourtneyBVance tonite. Nominated for Best Spoken Word #Grammy, narrating my recent book "Accessory to War: The Unspoken Alliance Between Astrophysics & the Military". Stiff competition, though — including @TiffanyHaddish & @Questlove.

The #SuperBowl: Momentum & Energy transfer. Elastic & Inelastic collisions. Spin-stabilized Prolate Spheroids. American Football is Physics.

The @NFL’s #SuperBowl Sunday

Bad day to be a Chicken. But so is any other day. In the USA nearly 9-Billion Chickens are eaten per year. If you do the math, that’s a Million Chickens per hour.

Always thought it might be fun if the NFL added anther bowl game to the season, featuring only vegetarian players. They could then call it the “Salad Bowl”.

Apologies to the civilized world for my use of Fahrenheit. Please be patient with us in America as we inch towards the metric system.

Color photo with no color in it — just shades of sepia. My living room suspension lamp from Artemide, for which the light source may be more intriguing than whatever it’s trying to illuminate. For me, it evokes Saturn and its ring system.

I own about 100 cosmic ties & vests. Think that’s geeky? it's camouflage when I hang out with fellow astrophysicists. Behold @STARtorialist, https://t.co/E1VSEB3iXK, curated by colleagues @emilylurice & @Summer_Ash, your clearing house for blending in with the universe.

** MERRY PERIHELION **

Overnight January 2 / 3, 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 is why.

*** HELLO, HELLO! ***

January 1, 2019. The @NASANewHorizons spacecraft, launched in January 2006, encounters 20km wide Kuiper-Belt comet 2014-MU69, the farthest object we’ve ever seen close up.

Nicknamed “Ultima Thule,” a Medieval reference to “Beyond Known Lands.”

HAPPY NEW YEAR on the Gregorian Calendar.

January 1. An annually recurring day that carries no scientific significance whatsoever.

Roman Coin: The god Janus, looking forward & backwards, after whom the month of January was named.

***Happy Kwanzaa***

December 26 thru January 1. Dating from 1966, seven days that commemorate and celebrate the African Diaspora.

Kwanzaa translates from Swahili to “First Fruits of the Harvest”.
