Using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the HARPS-N spectrograph at the 3.6-m Telescopio Nazionale Galileo, astronomers have discovered and confirmed an ultra-short period keystone planet orbiting an M2 dwarf (red dwarf star) called TOI-1634 .

"Since its science operations began in July 2018, TESS has uncovered a wealth of transiting planet candidates whose orbital periods and radii lie within the radius valley , including three planets transiting early M-dwarfs: TOI-1235b, TOI-776b, and TOI-1685b," said Dr. Ryan Cloutier from the Harvard & Smithsonian Center for Astrophysics and his colleagues.

Pomona-born astronaut answers students’ questions from orbiting space station – Daily
Elijah Cole, a student at Etiwanda High School, asked Pomona-born astronaut Victor Glover to name the most beautiful thing he’s seen during his time aboard the International Space Station .
Glover, 44, a 1994 graduate of Ontario High School, which along with Etiwanda High is part of the Chaffey Joint Union High School District, didn’t hesitate:

Cosmic mouthful: Tasters savor fine wine that orbited Earth
BORDEAUX, France – It tastes like rose petals. It smells like a campfire. It glistens with a burnt-orange hue. What is it? A 5,000-euro bottle of Petrus Pomerol wine that spent a year in space.
Researchers in Bordeaux are analyzing a dozen bottles of the precious liquid – along with 320 snippets of Merlot and Cabernet Sauvignon grapevines – that returned to Earth in January after a sojourn aboard the International Space Station.

TESS discovers four exoplanets orbiting a nearby sun-like star | MIT News | Massachusetts
MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of their star, this system could be an ideal target for atmospheric characterization with NASA's upcoming James Webb Space Telescope. Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, led the study published in The Astronomical Journal on Jan. 25.
With further study, says Daylan, this bright star and its many planets could be critical to understanding how planets take shape and evolve. "When it comes to characterizing planetary atmospheres around sun-like stars, this is likely one of the best targets we will ever get," he says of the results he presented earlier in the month at the 237th meeting of the American Astronomical Society.
Orbiting, Another Thing for Online Daters to Worry About - The New York Times
If you've dated in the age of social media — particularly now that you've pivoted from posting the occasional status update to running 24/7 multiplatform documentaries of your existence — chances are you've been watched, liked and followed by a crush, a lover or an ex.
Prying eyes on Instagram, Snapchat and Twitter can be exciting when they come from a prospective romantic partner, confusing when unrequited and infuriating when the looker is an ex. In the last case, it's as though the specter of a Relationship That Could Have Been is peeping over your shoulder, keeping tabs without having to commit to any real-world interactions.
Scientists spot 6 alien worlds orbiting a star in strange — but precise — harmony | Space
The planets around a star called TOI-178 know how to keep a beat — so smoothly, in fact, that scientists were able to discover new alien worlds by deciphering the system's music.
Astronomers poring through data from NASA's Transiting Exoplanet Survey Satellite (TESS) discovered three planets around a star dubbed TOI-178 (TOI stands for TESS Object of Interest). And when scientists looked at these observations more closely, they realized that the worlds seemed to be keeping time against each other. So they recruited some more instruments — and discovered the system hosts at least six planets, five of which tick off orbits in rhythm with the others.
Oddities of Orbits & Distance Help Connect Us to Our World
Back in the dark corners of your memory, behind the list of all the state capitals and the seven times table, you probably remember what you learned in grade school – about 93 million miles.
Like most things, the truth isn't quite so simple. In 1609, the German super-genius Johannes Kepler brought the world the first of his three laws of planetary motion. It says that the planets all travel in elliptical – not circular – orbits. This puts the sun off-center, and means that orbits are stretched out, and slightly egg-shaped.
