What Is Quantum Gravity?

Gravity was the first fundamental force that humanity recognized, yet it remains the least understood. Physicists can predict the influence of gravity on bowling balls, stars and planets with exquisite accuracy, but no one knows how the force interacts with minute particles, or quanta. The nearly century-long search for a theory of quantum gravity — a description of how the force works for the universe’s smallest pieces — is driven by the simple expectation that one gravitational rulebook should govern all galaxies, quarks and everything in between.

Nanoparticles could someday give humans built-in night vision

Movies featuring heroes with superpowers, such as flight, X-ray vision or extraordinary strength, are all the rage. But while these popular characters are mere flights of fancy, scientists have used nanoparticles to confer a real superpower on ordinary mice: the ability to see near-infrared light. Today, scientists report progress in making versions of these nanoparticles that could someday give built-in night vision to humans.

The researchers will present their results at the American Chemical Society (ACS) Fall 2019 National Meeting & Exposition.

“When we look at the universe, we see only ,” says Gang Han, Ph.D., the project’s principal investigator, who is presenting the work at the meeting. “But if we had near-infrared vision, we could see the universe in a whole new way. We might be able to do infrared astronomy with the , or have without bulky equipment.”

5 Realities Space Advocates Must Face

This new frontier of space remains fraught with some hard realities.

Hubble Celebrates Spitzer’s 16th Birthday

To celebrate NASA’s Spitzer Space Telescope’s 16th birthday, the Hubble Space Telescope team decided to put together a special present for their fellow “observing buddy.”

Hubble and Spitzer have observed many of the same astronomical objects over the years; and with Spitzer getting data from infrared, and Hubble getting data from visible, ultraviolet, and some near-infrared, the two telescopes have helped uncover some of the mysteries of the universe.

Russian Capsule Carrying Humanoid Robot Fails to Dock at Space Station

A Russian Soyuz spacecraft carrying a humanoid robot failed to dock with the International Space Station (ISS) on Saturday morning, Russian state news agencies reported.

The Soyuz MS-14 crew ship launched from the Baikonur Cosmodrome in Kazakhstan on August 21 with the Skybot F-850, a life-sized artificially intelligent humanoid robot, on the commander’s seat.

Given the issues, emerged during the docking of the #SoyuzMS14 spacecraft with the ISS, the state commission chaired by Roscosmos Director General Dmitry Rogozin will held a meeting to consider the situation and discuss the measures to overcome the fault in the docking system. pic.twitter.com/turpSi08Rf

First Vulcan to Launch America’s Return to the Moon with ‘Peregrine’ Lander in 2021

It’s a lunar lander named ‘Peregrine’, developed by the space robotics company to deliver payloads to the Moon for various companies, governments, universities, non-profits, and individuals for $1.2 million per kilogram. Astrobotic was selected by NASA in May 2019 for a $79.5 million contract to deliver up to 14 payloads to the Moon in 2021, under the agency’s Commercial Lunar Payload Services (CLPS) program.

To date, Astrobotic has signed 16 customers for lunar delivery on that first mission, totaling 28 payloads from 8 nations and comprising resource development, scientific investigation, technology demonstration, exploration, marketing, arts, and entertainment. The vehicle has already passed an industry-standard Preliminary Design Review, and the program will build and test a Structural Test Model, followed by a Critical Design Review, later this year.

Launch is currently slated for June 2021, with a planned landing a month later in Lacus Mortis, a large crater on the near side of the Moo n with payloads such as instruments to conduct new lunar science, pinpoint lander position, measure the lunar radiation environment, assess how lander and astronaut activity affects the Moon, and assist with navigation precision, among other capabilities.

Why Pluto is no longer a planet (or is it?)

Pluto was long considered our solar system’s ninth planet. Although small, it orbits the sun and has the spherical shape required to be considered a planet.

But today marks 13 years since Pluto received a harsh drop in status — officially dubbed Pluto Demotion Day.

Pluto was relegated in 2006 when the International Astronomical Union (IAU) created a new definition for planets and decided Pluto did not fit the bill.
