Infinity ² (vimeo)
from Uncage the Soul Productions

Something internal and personal draws us out to the night sky. Under a blanket of stars and the Milky Way arcing over head, we ask the simple question "What do you feel?"

This short film follows 20 high schoolers far from the city lights to an Astronomy Camp; then joins the Oregon Star Party where 600 astronomers camp out with telescopes of all sizes during the Perseids Meteor Shower. Timelapse has been the only way to showcase the night sky in video; but with the new low-light technology of the Canon MH20f-SH, we film in the quiet moments that have been impossible to capture until now.

NASA will host a teleconference at 2 p.m. EDT Monday, Sept. 26, 2016, to present new findings from images captured by the agency’s Hubble Space Telescope of Jupiter’s icy moon, Europa. (Spoiler alert: NOT aliens)

Gaia space telescope plots a billion stars
BBC.com

The most precise map of the night sky ever assembled is taking shape. Astronomers working on the Gaia space telescope have released a first tranche of data recording the position and brightness of over a billion stars. And for some two million of these objects, their distance and sideways motion across the heavens has also been accurately plotted.

Gaia's mapping effort is already unprecedented in scale, but it still has several years to run. Remarkably, scientists say the store of information even now is too big for them to sift, and they are appealing for the public's help in making discoveries.

To give one simple example of the scope of Gaia: Of the 1.1 billion light sources in Wednesday's data release, something like 400 million of these objects have never been recorded in any previous catalogue.

"You're imaging the whole sky in basically [Hubble] space telescope quality and because you can now resolve all the stars that previously maybe looked as though they were merged as one star at low resolution - now we can see them," explained Anthony Brown from Leiden University, Netherlands.

"The signal"
by "Pale Red Dot - A search for Earth-like planets around Proxima Centaury"

"So while we are convinced there is a signal in the Doppler measurements of Proxima, previous data do not allow to confirm its presence and clarify its origin. The long term variability of Proxima spoiled our attempts to combine data from previous observations so we needed a dedicated campaign. Combination of UVES and HARPS data at different cadences suggest that the star is showing a smoothly varying Doppler signal. Since the UVES survey set an upper limit between 2-3 Earth masses and if the signal is not activity induced, it must correspond to a planet smaller than that (between 1-2 Earth masses). The signal might well be caused by stellar activity, which should be quasi-periodic as opposed to the strict periodicity of the orbital motion of a putative planet. [...]"

Relative Likelihood for Life as a Function of Cosmic Time
by Abraham Loeb, Rafael A. Batista, David Sloan
http://arxiv.org/abs/1606.08448 (27 Jun 2016)


Is life most likely to emerge at the present cosmic time near a star like the Sun? We address this question by calculating the relative formation probability per unit time of habitable Earth-like planets within a fixed comoving volume of the Universe, dP(t)/dt, starting from the first stars and continuing to the distant cosmic future. We conservatively restrict our attention to the context of "life as we know it" and the standard cosmological model, LCDM. We find that unless habitability around low mass stars is suppressed, life is most likely to exist near 0.1 solar-mass stars ten trillion years from now . Spectroscopic searches for biosignatures in the atmospheres of transiting Earth-mass planets around low mass stars will determine whether present-day life is indeed premature or typical from a cosmic perspective.
