Updates From Space

A Spring day….cool temps and sun…..the garden loves it and MoMo is busy……

Yes I know….but I have been fascinated with all things space since my early years…..I watch because few others do……

The new planet hunter scores big……

The signals collected by TESS were followed up by the Planet Finder Spectrograph (PFS) on the Magellan II telescope at the Las Campanas Observatory in Chile. PFS has the ability to provide astronomers with estimates for the mass of exoplanets. As revealed in The Astrophysical Journal Letters, the sub-Neptune HD 21749b weighs around 23 Earths and has 20 times the volume of our planet.

This warm giant planet orbits its star every 36 days. While this is a small number compared to the planets in the Solar System (Mercury, for example, orbits the Sun in 88 days), HD 21749b’s is the longest orbital period among the planets detected by TESS. Most of the planets found by this mission are expected to have orbital periods of fewer than 10 days, so the analysis of this object was actually more complex than expected.

Star Wars fans have had their dream come true (well maybe a small one)

“Tatooine” found!

The only known multiplanet “Tatooine” system just got even more interesting.

A third world lurks in the two-star Kepler-47 system, and it’s bigger than its two previously discovered siblings, a new study reports.

“We certainly didn’t expect it to be the largest planet in the system,” study co-author William Welsh, an astronomer at San Diego State University (SDSU), said in a statement. “This was almost shocking.”

BTW,,,Tatooine is a place in Tunisia……FYI

Saturn’s moon Titan is a popular place in astronomy…….

It’s been well over a year since NASA’s incredibly trusty Cassini probe performed its final act, plunging into Saturn’s atmosphere where it was obliterated by the intense friction. It was a bittersweet day for the astronomy community, but the wealth of information Cassini gathered during its over 13 years orbiting Saturn is still yielding new discoveries.

\In a new paper published in Nature Astronomy, researchers on the Cassini project reveal that the spacecraft’s bounty of radar data now shows that Saturn’s moon Titan are even more special than scientists already realized. The moon’s lakes, which were observed by Cassini during its final pass in 2017, are far deeper than anyone thought.

Space is not the final frontier but it is getting a lot more crowded.  I watch because so many do not.

My day is full of yard work and to MoMo’s whims…..have a great Saturday.

  1. In the late 80’s early 90’s (my oldest was about 10 at the time) my son got me into SETI@home. It’s still being done.. University of California. The program was allowing for people to download a program that would interface with a SETI mainframe.. thus allowing the home user to grab a portion of the “recorded” space noise collected by SETI-dedicated radio-telescopes and use their own home computer CPU time, like when you were sleeping, to analyze the data… and you could watch the progress on your home screens. Cool stuff back in the day.. and even now actually. My son went on to work at the Adler Planetarium in Chicago and is in the running for a directorship. He found his niche in astronomy and keeps up on this stuff. I totally agree, chuq.. I had my telescopes in the past as I was growing up too. Except growing up in Chicago meant a lot of light pollution.
