This map shows the geographic distribution of the mobile towers of planet Earth, represented by red dots. The map contains more than 30 million individual data points, most of which

Top: an example of a chop-subtraction image pair from VLT/NEAR. Image B, following 0.05 sec after A, is subtracted to remove the detector bias, thermal background, AGPM glow, and excess

Earth’s stratosphere — NASA Although the high-altitude limit for microbial survival in the Earth–atmosphere system has remained a scientific curiosity and topic of study, the ecological significance of long-distance microbial

True colour image of a cloud-free Ocean planet at α = 90◦with different surface wind speed maps. In the first row, we use a constant wind speed and notice the

Observational HR diagram, from Hipparcos data, of stars within 10 pc of the Sun. The black box isolates the parameter range +4.0 MV +6.5 and +0.50 (B-V) +1.05 (see text)

Plurality Of Worlds, Leonhard Euler (1744) This paper provides an overview of recent historical research regarding scientifically-informed challenges to the idea that the stars are other suns orbited by other

This schematic depicts the set-up of the volatile exchange during initialization (t=0) and run time. For initialization, a surface temperature of 4000 K and a completely molten magma ocean is

The LSST throughput curves across the ugrizybands (colored lines) represent the combined effects of the Rubin Observatory system4, including mirrors, lenses, filters, detectors, and a fiducial atmosphere at 1.2 airmasses
