Tabby’s Star – KIC 8462852 – remains one of the more interesting and mysterious objects in the sky. There is a good update at “Updates on Boyajian’s Star” – Astrowright’s blog and “Bradley Schaefer: Further Thoughts on the Dimming of KIC 8462852” at Centauri Dreams has the latest on the controversy over whether the star…

A New Kepler Orrery

Ethan Kruse has update the Kepler Orrery, just in time for Extreme Solar Systems III now under way. Enjoy

The Dance of Neptune

The Kepler 2 mission serendipitously observed Neptune about a year ago. The images were posted on the K2 website, but according to the website stat like nobody shared them, which sucks. The animation was just shown at the Division for Planetary Sciences meeting, #DPS15, in DC so it is time to show it again. Enjoy.…

As of this morning we have discovered over 1,500 exoplanets, planets orbiting stars other than the Sun. In addition to the confirmed discoveries, we have over 3,000 candidate exoplanets, most discovered by the NASA Kepler Mission through transits, where we see the shadow of a planet as it crosses in front of its parent star.…

Distant Cousins: Kepler-186f

Big Eyed Beans from Venus – Captain Beefheart and his Magic Band! Cool. Literally Comparable to Mars in effective temperature, bit larger than Earth, probably slightly more massive than Earth (mean density could be lower), atmosphere unknown. Might well have extensive surface regions with persistent liquid water.

I come to praise Kepler, not to bury it… The Kepler Mission is one of the little NASA spacecraft that so frequently comes along, exceeds all expectations and changes our perspective of the universe. There is a good Quick History of the transit method and Kepler Mission concept on the website. Otto Struve noted in…

exoplanetology sundries

There were a number of interesting results reported today, the start of what promises to be an interesting week: IR spectra of HR 8799 planets – Scharf at SciAm blogs reports on the Oppenheimer et al paper using the P1640 at the Palomar telescope. Their interpretation of the rather low signal-to-noise low resolution spectra is…

The shadow of a shadow of a planet… and other fun Kepler discoveries Exoplanets in Multi-body Systems in the Kepler Era is a conference currently under way at the Aspen Center for Physics The meeting is very vibrant, with a mostly very young crowd of active researchers. There have been a number of very interesting…

To Do:

Given ηEarth=1 Find more terrestrial exoplanets. Find habitable terrestrial exoplanets. Find inhabited terrestrial exoplanets. Go visit. Consider the following snippets: Kepler discover 5 planets orbiting inside 0.1 AU Kepler: A Transiting Circumbinary Planet in a Quadruple Star System Terrestrial mass planet discovered around α Cen B Kepler exoplanet survey jeopardized Kepler has lost one of…

Comparative Exoplanetology

Why do we need to spend any more effort on extra-solar planets? We found some, they’re there. Lumps of rocks, gasballs. We’re done, right? This, loosely paraphrased, was a serious question I got last week. The context was a question of why I was spending serious effort on exoplanet research, rather than focusing exclusively on…
