A Farewell to Plutoshine Looking back at an overexposed Charon and Plutoshine. Credit: NASA/JPL/New Horizons Sometimes, its not the eye candy aspect of the image, but what it represents. A recent image of Pluto’s large moon Charon courtesy of New Horizons depicting what could only be termed ‘Plutoshine’ caught our eye. Looking like something from the grainy era of the early Space Age, we see a crescent Charon, hanging against a starry background… So what, you say? Sure, the historic July 14th , 2015 flyby of New Horizons past Pluto and friends delivered images with much more pop and aesthetic appeal. But look closely, andRead More →

Rogue NASA, EPA, NPS Twitter Accounts Launched to Protest Trump Directives Twitter page of Rogue NASA. Credit: Twitter Three federal agencies — the National Park Service, the EPA and now NASA — have allegedly launched unofficial “protest” accounts on Twitter in defiance of the Trump team’s directives to not blog, tweet or talk to the news media about climate changes issues. While it’s not unusual for a new administration to want to control the message, many bristle at what they see as an administration that wants to redefine and control scientific fact. That brings us to these accounts. Are they really created by NASA and otherRead More →

The vibration tests are conducted by the team on a shaker table at Goddard to ensure Webb’s worthiness and that it will survive the rough and rumbling ride experiencedRead More →

Galactic Stripping Mystery Uncovered It’s what you might call a case of galactic homicide (or “galacticide”). All over the known Universe, satellite galaxies are slowly being stripped of their lifeblood – i.e. their gases. This process is responsible for halting the formation of new stars, and therefore condemning these galaxies to a relatively quick death (by cosmological standards). And for some time, astronomers have been searching for the potential culprit. But according to a new study by a team of international researchers from the International Center for Radio Astronomy Research (ICRAR) in Australia, the answer may have to do with the hot gas galactic clustersRead More →

Japan Becomes A Military Space Player With Latest Launch The Japanese Aerospace Exploration Agency (JAXA) has accomplished some impressive things over the years. Between 2003 (when it was formed) and 2016, the agency has launched multiple satellites – ranging from x-ray and infrared astronomy to lunar and Venus atmosphere exploration probes – and overseen Japan’s participation in the International Space Station. But in what is an historic mission – and a potentially controversial one – JAXA recently launched the first of three X-band defense communication satellites into orbit. By giving the Japanese Self-Defense Forces the ability to relay communications and commands to its armed forces,Read More →

Could NASA Be Muzzled Under Trump Administration? The Trump Administration appears to be trying to change how government agencies disseminate information to the public. According to reports from multiple outlets, several agencies are being told to discontinue or suppress communications with the public, the media and even Congress. Additionally, Reuters is reporting that the Trump administration has instructed the Environmental Protection Agency (EPA) to remove information about climate change from its website. All this has anyone interested in NASA’s activities wondering if the US space agency could be ordered to stifle its very active social media presence, or to remove the extensive information it hasRead More →

The Carina Constellation Welcome back to Constellation Friday! Today, in honor of the late and great Tammy Plotner, we will be dealing with the “keel of the ship”, the Carina constellation! In the 2nd century CE, Greek-Egyptian astronomer Claudius Ptolemaeus (aka. Ptolemy) compiled a list of all the then-known 48 constellations. This treatise, known as the Almagest, would used by medieval European and Islamic scholars for over a thousand years to come, effectively becoming astrological and astronomical canon until the early Modern Age. One of these constellations, known as Argo Navis, would eventually be divided into three asterism  – one of which became the southernRead More →

What is the Alcubierre “Warp” Drive? It’s always a welcome thing to learn that ideas that are commonplace in science fiction have a basis in science fact. Cryogenic freezers, laser guns, robots, silicate implants… and let’s not forget the warp drive! Believe it or not, this concept – alternately known as FTL (Faster-Than-Light) travel, Hyperspace, Lightspeed, etc. – actually has one foot in the world of real science. In physics, it is what is known as the Alcubierre Warp Drive. On paper, it is a highly speculative, but possibly valid, solution of the Einstein field equations, specifically how space, time and energy interact. In thisRead More →

NASA: 2016 Was the Warmest Year on Record… Again! The reality of Climate Change has become painfully apparent in recent years, thanks to extended droughts in places like California, diminishing water tables around the world, rising tides, and coastal storms of increasing intensity and frequency. But perhaps the most measurable trend is the way that average global temperatures have kept rising year after year. And this has certainly been the case for the year of 2016. According to independent analyses provided by NASA’s Goddard Institute for Space Studies (GISS) and the National Oceanic and Atmospheric Agency (NOAA), 2016 was the warmest year since modern recordRead More →

Adventures With “Copyscope” Presenting… Copyscope. Image credit: Dave Dickinson Every telescope has a story to tell, and our discovery of Copyscope sent us on an interesting detective tale. We returned back to the U S of A recently, and one of our first tasks upon re-establishing our lives back in Florida was to dig through the archaeological strata that is our storage unit. Headlamp on and Leatherman in hand, we worked our way hacking through layers put in place over years of storage unit drop-off runs. On one hand, it’s like Xmas all over again, as you rediscover all your stuff anew. But on theRead More →
