Astronomy: September 2013 Archives

Keith's 11 Sep 7:00 pm EDT note: Looks like NASA will admit on Thursday that Voyager 1 has indeed left our solar system, but that it did so more than a year ago. NASA prefers Yes/No answers i.e. has it or has it not crossed that imaginary dotted line that is in place around the edge of our solar system.

The press event will be at 2:00 pm EDT. NASA has still not sent out a media advisory.

What's sort of funny is how all of the science types go back and forth as to whether Voyager 1 has or has not crossed this imaginary line that marks the boundary of our solar system - when no one has never been to the place where that line is - and the line is based on things we expect to find - but we don't exactly know when/where that magic line crossing will actually happen (or have already happened).

What I want to know is when Voyager 1 becomes VGER. Just wondering.

Jonathan McDowell agrees and wants NASA to rename Voyager 1 as "VGER" now - i.e. "Voyager Grand Extrasolar Recon".

Keith's 12 Sep 11:00 am EDT update: NASA PAO finally squeezed out a media advisory.

NASA News Conference Today To Discuss Voyager Spacecraft

"NASA will host a news conference today at 2 p.m. EDT (11 a.m. PDT), to discuss NASA's Voyager mission. It is related to a paper to be published in the journal Science, which is embargoed until 2 p.m. EDT."

Confirmed: NASA's Voyager 1 is Travelling in Interstellar Space, NASA

"New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars."

Habitable Planets Around White Dwarfs: an Alternate Mission for the Kepler Spacecraft

"Our proposed survey requires a total of 200 days of observing time, and will find up to 100 planets in the white dwarf (WD) habitable zone. This survey will maintain Kepler's spirit of searching for habitable Earths, but near new hosts. With few-day observations and minute-cadences per field, it will also open up a completely unexplored discovery space."

Keith's 3 Sep update: Additional Kepler white papers have been posted.

- Kepler: Searching The Habitable Zones of the Brightest Stars
- Kepler: Asteroseismology of Solar-Like Oscillators in a 2-Wheel Mission
- Kepler: Monitoring young associations and open clusters with Kepler in two-wheel mode
- The Kep-Cont Mission: Continuing the observation of high-amplitude variable stars in the Kepler field of view
- The Kepler-SEP Mission: Harvesting the South Ecliptic Pole large-amplitude variables with Kepler

Keith's 4 Sep update: Even more Kepler white papers have been posted.

- NEOKepler: Discovering Near-Earth Objects Using the Kepler Spacecraft
- Searching for Terrestrial Planets Orbiting in the Habitable Zone of Ultra-Cool Stars and Brown Dwarfs
- New Uses for the Kepler Telescope: A Survey of the Ecliptic Plane For Transiting Planets and Star Formation
