Message 1472847 - Posted: 5 Feb 2014, 0:46:48 UTC - in response to Message 1462128.  

Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA's planet-hunting Kepler space telescope.

No Thanks. Astronomers say, though it’s in no danger of falling down.

A wobbly planet would not support intelligent life as we know it.

What exactly constitutes an Earth doppelganger?

This, and future missions in the search for exoplanets.

i am pretty sure if we would be at 2,000 light years from here and try to find an exoplanet here , we wouldnt find nor the earth, but also wouldnt find Jupiter nor Saturn.

Why i think that ?

cause the earth does a 365 days revolution. and Jupiter 12 years and Saturn 29 years.

you need to find a dim change of light from our Sun every 365days or 12years/ 29years

we need datas over a 100years period of all stars of our galaxy.
we would be already dead by then ^^



Now you're only speaking of the gravitational microlensing technique:)

[edit] The Doppler technique, excuse me. Not possible for earth like planets unfortunately...

none of our planets can make the sun move in order to get a doppler effect.
mercury venus earth mars are too small, jupiter saturn uranus are too far.

i m talking transit

The planets in our solar system very definitely do make our sun move... Look up solar barycentre... There is a nice plot showing how the gravitational centre of our solar system is sometimes OUTSIDE the volume of our sun.

All that gives a very nice Doppler signal...


(And the optical occlusion of a transit is a different effect.)

Keep search in,

I just attended a lecture on the Kepler telescope given by Dr. Jeffrey Coughlin, a NASA scientist, who live locally and telecomutes. He stated among other things that the "fix" called K2 is currently gathering data. So that is very good news.

Astronomy is often a long term game. The people who dicovered the oldest star so far known , the Methuselah star," cataloged as H D 140283, have been looking for 30 years.
This is something we at SETI need to keep mind.

Message 1482017 - Posted: 26 Feb 2014, 19:02:09 UTC - in response to Message 1481872.  

NASA's Kepler mission announced Wednesday the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.

Nearly 95 percent of these planets are smaller than Neptune, which is almost four times the size of Earth. This discovery marks a significant increase in the number of known small-sized planets more akin to Earth than previously identified exoplanets, which are planets outside our solar system.

To be clear. Neptune is a gas giant that is 17 times more massive than the Earth. It is way way out of the habitable zone of our Sun.

I would like to see them find a truly Earth like planet

Earth-like planets, they found already. It's just to find a planet that has the same or similar properties to harbour (intelligent) life

It is important for all of us to define what we mean when we say "Earth-Like"

It is far more than finding one that is only a few times as big as Earth in my opinion.

My personal definition of earth-like planets is rocky planets orbiting the star in its habitable zone with perfect conditions for life to manifest and evolve.

Message 1506713 - Posted: 20 Apr 2014, 22:26:33 UTC

A white dwarf is acting like a magnifying glass in space according to data from NASA’s Kepler spacecraft.

http://www.nature.com/news/white-dwarf-acts-as-cosmic-magnifying-glass-1.15072

Using data from NASA’s Kepler spacecraft, physicists Ethan Kruse and Eric Agol of the University of Washington in Seattle observed an increase of just 0.1% in the larger star's brightness every 88 days, lasting for 5 hours. They say that the effect is the result of an orbiting white dwarf — a dense, compact, burnt-out star whose gravitational effects act as a magnifying glass every time it crosses the line of sight between its companion star and Earth. Kruse and Agol publish their findings in Science today.


Cheers.

Solar power gives planet hunter Kepler new life

Extended mission will search the ecliptic for exoplanets, star clusters, supernovae, and galaxies.

After being crippled when two of its four reaction wheels failed, the Kepler spacecraft, launched to find planets orbiting other stars, is back in action through innovative use of solar power.
