Scientists Are Using the Universe as a "Cosmological Collider"2017-22 | www.cfa.harvard.edu/

Physicists are capitalizing on a direct connection between the largest cosmic structures and
the smallest known objects to use the universe as a "cosmological collider" and investigate new physics.

The three-dimensional map of galaxies throughout the cosmos and the leftover radiation from the Big Bang –
called the cosmic microwave background (CMB) – are the largest structures in the universe that astrophysicists
observe using telescopes. Subatomic elementary particles, on the other hand, are the smallest known objects in
the universe that particle physicists study using particle colliders.

A team including Xingang Chen of the Harvard-Smithsonian Center for Astrophysics (CfA), Yi Wang from the Hong
Kong University of Science and Technology (HKUST) and Zhong-Zhi Xianyu from the Center for Mathematical Sciences
and Applications at Harvard University has used these extremes of size to probe fundamental physics in an
innovative way. They have shown how the properties of the elementary particles in the Standard Model of particle
physics may be inferred by studying the largest cosmic structures. This connection is made through a process
called cosmic inflation.

NASA’s Hubble Sees Martian Moon Orbiting the Red Planet

The sharp eye of NASA's Hubble Space Telescope has captured the tiny moon Phobos during its orbital trek around Mars.
Because the moon is so small, it appears star-like in the Hubble pictures.

Over the course of 22 minutes, Hubble took 13 separate exposures, allowing astronomers to create a time-lapse video
showing the diminutive moon's orbital path. The Hubble observations were intended to photograph Mars, and the moon's
cameo appearance was a bonus.

Ground-based images of planets obtained by Pic-Net Pro-Am team
https://phys.org/news/2017-07-ground-based-images-planets-pic-net-pro-am.html

The first observing run of a collaboration between amateur and professional astronomers to monitor
our planetary neighbours has resulted in some of the best planetary images ever taken from the ground.

The 'Pic-Net' project (http://pic-net.org/) aims to use the one-metre diameter planetary telescope at the Pic du Midi Observatory in the French Pyrenees
to monitor the meteorology of planets in our Solar System, measure global winds in their atmospheres, monitor impact of minor planet bodies producing giant
fireballs in planetary atmospheres, and provide observational support for various space missions. Last month, a small team of amateur astronomers carried
out a pilot observing run during a workshop funded by the Europlanet 2020 Research Infrastructure (RI). Superb-quality images of Jupiter, Saturn, Venus
and Jupiter's moon Ganymede were obtained during four nights of observations, as well as images of Uranus and Neptune.

The SETI Institute and French startup Unistellar, announced a partnership today to commercialize a new telescope that promises to deliver
an unparalleled view of the cosmos to amateur astronomers, and provide the opportunity to contribute directly to cutting-edge science.

Unistellar’s new eVscope™ leverages “Enhanced Vision” imaging technology and now provides three unique features never before offered in
a compact mass-market instrument thanks to this partnership.

"Our compact 4.5-inch telescope allows observers to see objects fainter than Pluto and achieve sensitivity equivalent to a one-meter telescope!”"

What is the Probability of Other Technological Species?

Can there be other technological civilizations in our Milky Way Galaxy?

Tune in this week as we discuss with Dr. Adam Frank the cosmic frequency of technological species in the Universe.
Recent advances in exoplanet studies provide strong constraints on all astrophysical terms in the Drake Equation.
By modifying the form and intent of the Drake equation Dr. Frank shows that they can set a firm lower bound on the
probability that one or more additional technological species have evolved anywhere and at any time in the history
of the observable Universe.

Join Tony Darnell, Dr. Adam Frank, Dr. Svetlana Berdyugina and Dr. Jeff Kuhn for a great conversation about finding
life in the Universe.

Bad News for Life: TRAPPIST-1 Planets' Atmospheres May Have Been Destroyed
https://www.space.com/37530-trappist-1-planets-atmospheres-stripped.html

The potentially Earth-like planets in the TRAPPIST-1 system may not be so conducive to life after all, two new studies report.

Intense radiation and particles streaming from their host star have likely taken a huge toll on all seven of these worlds, even the three that
apparently lie within the "habitable zone," where liquid water could theoretically exist on a planet's surface, according to the new research.

"Because of the onslaught by the star's radiation, our results suggest the atmosphere on planets in the TRAPPIST-1 system would largely be destroyed,"
Avi Loeb, co-author of one of the studies, said in a statement. "This would hurt the chances of life forming or persisting," added Loeb, who chairs
Harvard's astronomy department and who also works at the Harvard-Smithsonian Center for Astrophysics (CfA).
