The Dream of Faster-than-Light (FTL) Travel: Dr. Harold “Sonny” White and Limitless Space

Ever since astronomers found that Earth and the Solar System are not unique in the cosmos, humanity has dreamed of the day when we might explore nearby stars and settle extrasolar planets. Unfortunately, the laws of physics impose strict limitations on how fast things can travel in our Universe, otherwise known as Einstein’s General Theory of Relativity....

A new Quantum Technique Could Enable Telescopes the Size of Planet Earth

There’s a revolution underway in astronomy. In fact, you might say there are several. In the past ten years, exoplanet studies have advanced considerably, gravitational wave astronomy has emerged as a new field, and the first images of supermassive black holes (SMBHs) have been captured. A related field, interferometry, has also advanced incredibly...

Voyager 1 Doesn’t Know Where it is, Generating Random-Looking Telemetry Data

Old computer systems have a lot of wacky ways to fail. Computers that are constantly blasted by radiation have even more wacky ways to fail. Combine those two attributes, and eventually, you’re bound to have something happen. It certainly seems to have with Voyager 1. The space probe, which has been in active service for NASA for almost 45 years, is...

The Building Blocks for Supermassive Black Holes are Found in Dwarf Galaxies

We all know that a humongous black hole exists at the center of our galaxy. It’s called Sagittarius A* (Sgr A* for short) and it has the mass of 4 million suns. We’ve got to see a radio image of it a few weeks back, showing its accretion disk. So, we know it’s there. Astronomers can chart its actions as it gobbles up matter occasionally and they can...

“Wind-Ruffled Waves, Foam and Wave Shadows, Above Natural Blue Seawater.” This is how we’ll Spot Exoplanets With Oceans

Our planet’s oceans generate tell-tale light signatures when sunlight reflects off them. Exoplanets with significant ocean coverage may do the same. Can we use the Earth’s reflectance signatures to identify other Earth-like worlds with large oceans? We should be able to, eventually. A new study examined light signatures reflecting...

Solar Orbiter’s Pictures of the Sun are Every Bit as Dramatic as You Were Hoping

On March 26th, the ESA’s Solar Orbiter made its closest approach to the Sun so far. It ventured inside Mercury’s orbit and was about one-third the distance from Earth to the Sun. It was hot but worth it. The Solar Orbiter’s primary mission is to understand the connection between the Sun and its heliosphere, and new images from the close approach...

Update on the Potential May 31st tau Herculid Meteor Storm

If skies are clear, be sure to watch for a potential tau Herculid meteor outburst early next Tuesday morning. With a little cosmic luck, we could potentially be in for a meteor storm of epic proportions this coming Monday night/Tuesday morning. We recently wrote about the possibility for an outburst from the tau Herculids on the night of May...

The Moon’s Ancient Volcanoes Could Have Created Ice Sheets Dozens of Meters Thick

Everyone loves looking at the Moon, especially through a telescope. To see those dark and light patches scattered across its surface brings about a sense of awe and wonder to anyone who looks up at the night sky. While our Moon might be geologically dead today, it was much more active billions of years ago when it first formed as hot lava blanketed...

Spacesuits are Leaking Water and NASA is Holding off any Spacewalks Until They can Solve the Problem

NASA’s spacesuits are getting old. The extra-vehicular mobility units – EMUs for short – were designed and built for spacewalks outside NASA’s space shuttles, which flew for the last time in 2011. Nowadays, the EMUs are an integral part of maintaining and upgrading the International Space Station (ISS) exterior, providing the crew with the ability to...

Starliner Launches Successfully, but Two of its Thrusters Failed

Last week, Boeing’s next-generation CST-100 Starliner took off from Space Launch Complex 41 at Cape Canaveral, reached orbit, and docked with the International Space Station (ISS). Designated Orbital Flight Test-2 (OFT-2), this uncrewed test flight successfully validated the reusable space capsule for NASA’s Commercial Crew Program (CCP). This program,...
