❝ From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, ‘Look at that, you son of a bitch‘.

NASA scientists are releasing new global maps of Earth at night, providing the clearest yet composite view of the patterns of human settlement across our planet.
Satellite images of Earth at night — often referred to as “night lights” — have been a gee-whiz curiosity for the public and a tool for fundamental research for nearly 25 years. They have provided a broad, beautiful picture, showing how humans have shaped the planet and lit up the darkness. Produced every decade or so, such maps have spawned hundreds of pop-culture uses and dozens of economic, social science and environmental research projects…
In the years since the 2011 launch of the NASA-NOAA Suomi National Polar-orbiting Partnership satellite, Román and colleagues have been analyzing night lights data and developing new software and algorithms to make night lights imagery clearer, more accurate and readily available. They are now on the verge of providing daily, high-definition views of Earth at night, and are targeting the release of such data to the science community later this year.
Wow. Worth looking forward to.
Roughly the size of a basketball court, NASA’s Juno probe departed in 2011, hurtled through space for five years and finally made itself comfortable in Jupiter’s orbit in July 2016.
Now, at about 415 million miles from Earth, it has made its fifth close flyby of the Gas Giant and the images it sent home are breathtaking…
So far, they’ve discovered what Jupiter’s poles look like for the first time and are continuing to study the swirling clouds and storms covering the planet’s atmosphere (it’s thought they might be linked to complicated currents from the planet’s moon, Io)…
Traveling 129,000 miles per hour, Juno itself will never get closer than 2,700 miles from the cloud tops. Though that seems far, the data from the probe has already allowed scientists to rewrite what they thought they knew about giant planets and, possibly, the origins of our entire solar system.
No space travel available for cranky old geeks like me; so, photos like these are the next best thing. That and the creative minds of folks making movies with great CGI, nowadays.

❝ Ice loss from Canada’s Arctic glaciers has transformed them into a major contributor to sea level change, new research by University of California, Irvine glaciologists has found.
From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent, from an average of three gigatons to 30 gigatons per year, according to results published…in the journal Environmental Research Letters…
❝ The team found that in the past decade, overall ice mass declined markedly, turning the region into a major contributor to sea level change. Canada holds 25 percent of all Arctic ice, second only to Greenland…
❝ The Canadian ice cap has glaciers on the move into the Arctic Ocean, Baffin Bay and Nares Strait. The researchers used satellite data and a regional climate model to tally the “balance” of total gain and loss each year, and the reasons why. Because of the huge number of glaciers terminating in area marine basins, they expected that discharge into the sea caused by tide water hitting approaching glacier fronts would be the primary cause.
In fact, they determined that until 2005, the ice loss was caused about equally by two factors: calving icebergs from glacier fronts into the ocean accounted for 52 percent, and melting on glacier surfaces exposed to air contributed 48 percent. But since then, as atmospheric temperatures have steadily climbed, surface melt now accounts for 90 percent.
❝ Lead author Romain Millan said that in recent years ice discharge was only a major component in a few basins, and that even rapid, short term increases from these ice fields only had a minor impact on the long-term trend.
Millan added, “We identified meltwater runoff as the major contributor to these ice fields’ mass loss in recent years…
Just keeping y’all up-to-date, folks. Climate change deniers won’t spend any of their bought-and-paid-for time checking scientific study. Folks with a real interest in real science enjoy the practice.

❝ RADIO signals emerging from the newly-discovered ‘TRAPPIST-1’ planetary system have been decoded by linguistic experts at NASA, confirming the existence of extraterrestrial lifeforms who want ‘no part of Earth’s bullshit’.
❝ There was great excitement from astronomy enthusiasts earlier this week following the discovery of seven planets in the ‘habitable’ zone of a nearby solar system; planets which seemingly had all the criteria for supporting life.
However, this was eroded somewhat today when NASA announced that lifeforms on the third of these planets seemed to be ‘standing very still as if not to be noticed’, much like how someone would hide behind the sofa in their house if a TV licence inspector or debt collector came to the door.
❝ …A signal from the planet was received and later translated, and appears to show that the alien lifeforms were well aware of the existence of Earth.
“The transmission begins ‘Oh fucking bollocky bollocks’” said a spokesperson for NASA…
❝ “‘They’ve found us, well that’s just tickety-fucking-boo’. The conversation then breaks down into a series of back-and-forth arguments where the aliens appear to blame each other for being found, with one very vocal creature appearing to be furious that Earthlings may now attempt to travel to the new planet. ‘Why did you have to have the telly on so fucking loud?’, they say”.

❝ How do you know when spring has begun? Is it the appearance of the first tiny leaves on the trees, or the first crocus plants peeping through the snow? The Spring Leaf Index is a measure of these early season events in plants, based on recent temperature conditions. This model allows us to track the progression of spring onset across the country. The map shows locations that have reached the requirements for the Spring Leaf Index model (based on NOAA National Centers for Environmental Prediction Real-Time Mesoscale Analysis temperature products).
