This infographic illustrates key features of the TOI 270 system, located about 73 light-years away in the southern constellation Pictor. The three known planets were discovered by NASA’s Transiting Exoplanet Survey Satellite through periodic dips in starlight caused by each orbiting world. Insets shows information about the planets, including their correct relative sizes, and how they compare to Earth. Temperatures given for TOI 270 planets are equilibrium temperatures, calculated without the warming effects of any possible atmospheres. Credit: NASA’s Goddard Space Flight Center/Scott Wiessinger

NASA’s TESS discovered three new planets nearby, including temperate ‘sub-Neptune’

NASA’s Transiting Exoplanet Survey Satellite, or TESS, has discovered three new planets that are among the smallest, nearest exoplanets known to date.

Panorama view of Apollo 12 lunar surface photos Panorama view of Apollo 12 lunar surface photos with lunar module pilot Alan L. Bean and the TV taken from just inside the rim of Surveyor Crater on the first moonwalk of the mission. The panoramas were built by combining Apollo 12 images starting with frame AS12-46-6777 thru end frame AS12-46-6780. The panoramic images received minimal retouching by NASA imagery specialists, including the removal of lens flares that were problematic in stitching together the individual frames and blacking out the sky to the lunar horizon. These adjustments were made based on observations of the Moon walkers who reported that there are no stars visible in the sky due to the bright lunar surface reflection of the Sun.

NASA released the stunning panorama of Apollo landing sites for the 50th anniversary

NASA imagery experts at NASA’s Johnson Space Center have “stitched together” images from the Apollo landing sites on the Moon for a 50th-anniversary reminder of what the 12 humans who walked on its surface experience visually.
These galaxies are selected from a Hubble Space Telescope program to measure the expansion rate of the universe, called the Hubble constant. The value is calculated by comparing the galaxies' distances to the apparent rate of recession away from Earth (due to the relativistic effects of expanding space). By comparing the apparent brightnesses of the galaxies' red giant stars with nearby red giants, whose distances were measured with other methods, astronomers are able to determine how far away each of the host galaxies are. This is possible because red giants are reliable milepost markers because they all reach the same peak brightness in their late evolution. And, this can be used as a "standard candle" to calculate distance. Hubble's exquisite sharpness and sensitivity allowed for red giants to be found in the stellar halos of the host galaxies. The red giants were searched for in the halos of the galaxies. The center row shows Hubble's full field of view. The bottom row zooms even tighter into the Hubble fields. The red giants are identified by yellow circles. Credit: NASA, ESA, W. Freedman (University of Chicago), ESO, and the Digitized Sky Survey

New Hubble constant measurement adds to mystery of universe’s expansion rate

In a new study, scientists announced a new measurement of the Hubble constant using a kind of star known as a red giant and indicated that the expansion rate for the nearby universe is just under 70 kilometers per second per megaparsec (km/sec/Mpc).
