Using spacecraft and ground-based facilities, Russian astronomers have inspected the Orion Bar photodissociation region, focusing on the mid-infrared emission from this source. Results of the study could help astronomers to better understand the evolution of polycyclic aromatic hydrocarbons in space. The research was published November 10 on arXiv.org.

At a distance of about 1,300 away, the Orion Nebula is the nearest of massive star formation to Earth, with a complex and extensive gas structure. It hosts the so-called “Orion Bar”—a ridge-like feature of gas and dust formed by the intense radiation from nearby, hot, young stars, which appears to be shaped like a bar.

The Orion Bar is a photodissociation region or photon-dominated region (PDR). In general, PDRs are regions in the interstellar medium (ISM) at the interface between hot ionized gas and cool molecular gas that are energetically dominated by non-ionizing ultraviolet photons.

Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. But imagine a telescope far away in the outer solar system, 10 or even 100 times farther from the Sun than Earth. The ability to look back at our solar system or peer into the darkness of the distant cosmos would make this a uniquely powerful scientific tool.

I’m an astrophysicist who studies the formation of structure in the universe. Since the 1960s, scientists like me have been considering the important scientific questions we might be able to answer with a telescope placed in the outer solar system.

So what would such a mission look like? And what science could be done?

The next full Moon is a near-total lunar eclipse, the Beaver, Frost/Frosty, or Snow Moon; Kartik Purnima, the full Moon of the Festivals of Karthika Deepam, Karthikai Vilakkidu, Thrikarthika, Loi Krathong, Bon Om Touk, and Tazaungdaing; and Ill (or Il) Poya.

The next full Moon will be early on Friday morning, November 19, 2021, appearing opposite the Sun (in Earth-based longitude) at 3:58 a.m. EST. While this will be on Friday for much of the Earth, it will be Thursday night from Alaska’s time zone westward to the International Date Line in the Pacific Ocean. The Moon will appear full for about three days around this time, from Wednesday night through Saturday morning.

This should be a good month for skywatching, with Venus.

Using ESA’s XMM-Newton and NASA’s Chandra X-ray space telescopes, astronomers have made an important step in the quest to find a planet outside of the Milky Way. Spotting a planet in another galaxy is hard, and even though astronomers know that they should exist, no planetary systems outside of…

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.”

Rumors that Tesla is indeed making a smartphone were bolstered after the world-famous design studio ADR released concept images (in a video). This made people wonder: Is Tesla going to go after the iPhone — or simply create an entirely new market segment, such as a true-to-form satellite phone that works where traditional WiFi or 5G services are absent, and able to mine cryptocurrencies anywhere, including on the planet Mars?While speculations abound, there are numerous unanswered questions, such as: how much would it retail for? Does it have a sim card? What’s the monthly charge for using Starlink? Can I buy one, without first buying a Tesla EV? Its release date is a closely-guarded secret. A Starlink antenna is being taken out of the box. Tech publications have leaked images of the new device supposedly out of the EV maker, including some details of what it can do.

Venus could actually be a second home to humanity someday.

Welcome back to our ongoing “Interplanetary” series. Today, we take a look at Earth’s “Sister Planet,” Venus! Given the extreme conditions present on this planet, you might say that Venus is the “evil sister” of Earth. And yet, people could live there someday in any number of ways. All it would take is the right kind of resources, dedication, and knowledge.

For generations, humans have been fascinated by Venus, the brightest star in the night and morning sky. Because of the nature of its appearance, where it disappears for days at a time and then appears to emerge on the other side of the Sun, it was long thought to be two different stars — the “Morning Star” and the “Evening Star.”

It was not long before ancient astronomers began to recognize that these “stars” were actually one and the same. As they kept track of Venus’ movements over generations and even centuries, they came to realize that Venus (like the other planets) was no star. And like the constellations of old, the planet began to give rise to its own myths and legends.

Full Story:

Pieces of a shattered Soviet-era satellite are visible in new telescope images after its destruction by a Russian anti-satellite weapons test on Monday (Nov. 15).

The images were captured by Numerica Corp., a Colorado-based company provides tracking of space debris objects, and shared by the company’s partner Slingshot Aerospace on Twitter. They show images and video of the debris in the wake of a direct-ascent anti-satellite test by Russia Monday that sent a missile from the ground to destroy a defunct satellite called Cosmos-1408.

The telescopic footage shows just some of the more than 1,500 trackable pieces of debris from Cosmos-1408 after its destruction by Russia. The U.S. Space Department, U.S. military officials and NASA administrator Bill Nelson are among the authorities condemning Russia for the act, which they said put the International Space Station at risk from the debris.
