“Pale Blue Dot” revisited

For the 30th anniversary of one of the most iconic views from the Voyager mission, NASA’s Jet Propulsion Laboratory in Pasadena, California, is publishing a new version of the image known as the “Pale Blue Dot.”

The updated image uses modern image-processing software and techniques while respecting the intent of those who planned the image. Like the original, the new color view shows Planet Earth as a single, bright blue pixel in the vastness of space. Rays of sunlight scattered within the camera optics stretch across the scene, one of which happens to have intersected dramatically with Earth.

The view was obtained on Feb. 14, 1990, just minutes before Voyager 1’s cameras were intentionally powered off to conserve power and because the probe – along with its sibling, Voyager 2 – would not make close flybys of any other objects during their lifetimes. Shutting down instruments and other systems on the two Voyager spacecraft has been a gradual and ongoing process that has helped enable their longevity.

RTFA. Offer your memory an opportunity to deepen your sense of proportion.

Here comes another piece of the future

Kudos to Elon Musk, his peers like Jeff Bezos, and many more not-so-public figures striving to move our species forward to better times.

US goverments lost any sense of science leadership decades ago. Not as good a vote-getter as 19th Century bible-thumping and bigotry. Congress remains more concerned with job security than justice, myths of pearly gates instead of education and health.

The hopes and praise fall to Elon Musk. An immigrant who got round to becoming a citizen in this millennium.

NASA Receives First Audio From New Planets

BREAKING NEWS, WORLD NEWS

❝ 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”.

NASA website hosts regularly updated Earth imagery


Click to enlarge

NASA has launched a new website allowing the public to view images snapped by its Deep Space Climate Observatory (DSCOVR) satellite. The service will provide multiple shots of stunning Earth imagery seven days a week, mere hours after capture.

DSCOVR is operated through a partnership between NASA, the National Oceanic and Atmospheric Administration (NOAA) and the US Air Force, with a mission to monitor space weather emanating from the Sun, and serve as a form of early warning system for potentially harmful events…

Images featured on the website are captured roughly 12 – 36 hours prior to release, and feature a simple graphic to the top left of the page informing users of the relative positions and distances of the DSCOVR satellite and our Sun. The page also displays a globe highlighting the landmasses that are in view.

Archived images will be accessible by searching for the subject’s capture date and the continents displayed in the image.

Sometimes the Web really brings you close to the beauty of science.

Celebrating Hubble’s 25th Anniversary

This visualization provides a three-dimensional perspective on Hubble’s 25th anniversary image of the nebula Gum 29 with the star cluster Westerlund 2 at its core. The flight traverses the foreground stars and approaches the lower left rim of the nebula Gum 29. Passing through the wispy darker clouds on the near side, the journey reveals bright gas illuminated by the intense radiation of the newly formed stars of cluster Westerlund 2. Within the nebula, several pillars of dark, dense gas are being shaped by the energetic light and strong stellar winds from the brilliant cluster of thousands of stars.

Happy anniversary, Hub. Waiting patiently for Webb to take over.
