The latter of two sets of interstellar radio missives were beamed out to the Cosmos on this day in 2003 from the RT-70 (Radio Telescope with an aerial antenna with a seventy metre diameter and former Soviet Centre for Deep Space Communications) located in Yevpatoria, Crimea. This iteration and the first message sent in 1999 follow the same bitmap structure and include the Dutil-Dumas primer about mathematics, universal constants, chemical elements and physics plus the Arecibo Messages, the Braastad Message (to illustrate concepts of family and procreation, similar to the plaque on Pioneer) and contributions from the staff and public. Transmitted at four hundred bits per second, the message was beamed out over the span of eleven hours and targeted five diverse stars with known exoplanets, with the first arrival date of April 2036 at Gliese 49 β, a superearth orbiting a red dwarf star.

First observed by sky-watchers in China on this day in 1054 (such temporary spectres were called generically “guest stars” 客星) and visible, easily to amateur astronomers to this day as the stellar remnant known as the Crab Nebula Supernova (SN) 1054 is perhaps one of the best known examples, though it’s nature and origin were unknown until very recently. Anticipating the return of Halley’s Comet in 1758 (see also), Charles Messier confused the static plerion for the returning traveller and was motivated by his mistake to create a catalogue of the celestial sphere, with the Crab Nebula labeled as the first Messier object, M1.

Co-founded by Stephen Hawking, Queen guitarist and astrophysicist Brian May and other former astronauts and technologists with the sanction of the United Nations, International Asteroid Day is an annual observance meant to promote awareness about the minor planets of the inner Solar System and the threats that these near-Earth objects can pose for cataclysm and ways to mitigate the vulnerability through close monitoring. 30 June was chosen as the date as it marks the anniversary of the 1908 Tunguska Event in the Eastern Siberia Taiga, an estimated twelve megaton explosion that flattened two thousand square kilometers of forest caused by the air burst of a meteoroid, devastating for local wildlife but spared greater catastrophe by dint of the region being sparsely populated by humans.

The first series of the science fiction genre to air on US television networks and running for nearly six years thanks to commercial sponsors and merchandising, Captain Video and His Video Rangers debuted on DuMont Television on this day in 1949. Receiving orders from the Commissioner of Public Safety, the rangers—operating from a terrestrial mountain-top base and defended peace and order on Earth as well as distant human colonies around other stars. The move off-world was prompted by learning that ABC was producing a series based on Buck Rogers, little did the television executives know that that show would be short-lived. Despite its popularity, originally airing Monday through Saturday, it was beset with budget and continuity problems for its entire run, often filling time on this rather fraught shooting schedule, the Video Ranger Communications Officer would show clips of cowboy movies from the Ancient West as training material, “undercover agents,” with little other explanation for padding the episodes. The entire network folded shortly after the series finished, Dumont regarded as the forgotten channel, most of its catalogue lost though the rare recording has been preserved.

Rather than pursue possibly risky and irreversible terrestrial geoengineering that might further ravage habitats and exacerbate the collapse of biomes, via TMN we learn that a group of researchers from MIT are hoping to create a thin film of deflective materials (easily deployable and reversible), like a parasol for our planet, that by just lessening the solar radiation that reaches us by two percent could give us the needed reprieve (in combination with efforts on other fronts, including serious lifestyle adjustments) to clean up our act.  More on MIT’s Senseable City Lab’s Space Bubble project at the link above.

orbital mechanics

Enunciated for the first time the following year after some concerted fact-checking and re-taking measurements since the outcome seemed to elegant to be true, Johannes Kepler discovered the last of his three laws of planetary motion on this day in 1618, capturing the relationship between the distance of a astronomical body from its host star and the time it takes to complete a trip around it: that is, the value of the cube of the semi-major axis divided by the square of a planet’s orbital period is a constant—for our solar system. The publication was also delayed due to rather laborious attempts to reconcile his formula with the theory of the music of the spheres (see here and also above), thus making this third discovery known as the harmonic law.

Though the Octave of Easter refers to a specific eight-day celebration in connect to the Paschaltide, our

word week itself (via the German Woche) derives from the same root as octave and that one out-of-cycle unit of time—that is, seemingly the sequence repeated for countless generations not determined by the motion of the Heavens or our perception of them but nonetheless in most Western and Eastern traditions named for the astronomical objects visible to the unaided eye. The ordering does not accord with the classical model of the Cosmos—the “Chaldean order” that describes the apparent overtaking and retrograde motion relative to the Earth—nor hierarchy of the pantheon, however, but rather the seven strings of the Mesopotamian lyre with which the celestial spheres were thought to harmonise: (4) Sunday ☉, (1) Monday ☽, (5) Tuesday ♂ (Mardi in French), (2) Wednesday ☿ (Mercoledì), (6) Thursday ♃ (Donnerstag), (3) Friday ♀ (Venres) and (7) Saturday ♄. Vexed somewhat by the onerous and complicated Roman subdivision of the days and the planetary officer appointed to each hours, the order of the weekdays seemingly recapitulates musical theory and progression through the major scale.

Coming home from Saxony we took a detour and finally got the chance to check out the Arche Nebra—a museum and planetarium near the archeological site where the prehistoric skydisc was discovered. The actual artefact is usually kept in Halle and was presently on loan to the British museum as part of an ancient astronomy exhibit that couples it with the megalithic timepieces like Stonehenge and the nearby counterpart, the Goseck circle, a solar observatory from neolithic times—but there were plenty of detailed replicas on hand to study and gain an appreciation in situ of this rather overwhelming tool. From the perspective of the promontory where it was discovered (Fundort), the golden bands ringing the edge form an arc precisely corresponding with the Sun’s pendular journey between the peak of the Brocken and the peak of the Kyffhäuser in the Harz rising and setting at the spring and autumn equinoxes and indicating by the appearance of the New Moon and its proximity to the Pleiades (see above) when to plant and whether the year will be a common year or will need an intercalary month inserted to keep the stars aligned with the cycle of the seasons, this earliest known representation of the Cosmos features no gods or heroes, only the calendar of the night sky. In the area, we also stopped at the village of Zingst on the Unstrut river to inspect this manor house by the road that looked like it had seen time conscripted as a factory with the addition of an industrial smoke-stack and the vista of the largest medieval castle complex—similar in scale and composition to the Wartburg—in middle Germany, Burg Querfurt, something to see another day.

Via Slashdot and a tranche of documents declassified by the US Space Command (previously) learn that one of Earth’s first encounters with an interstellar interloper happened fully three years prior to ‘Oumuamua with the explosive impact of a meteor strike that disintegrated in the Pacific off the coast of Papua New Guinea. The high speed (about sixty kilometres per second) and usual trajectory of the object place its origins outside of the Solar System. Confirmation was initially stymied due to data partially coming from a then-classified satellite that monitored for ballistic launches, but now confident of the object’s provenance, a mission to the bottom of the ocean is being entertained to search for fragments.

First spotted by Damn Interesting’s Curated Links, Scientific American reports that as the fiftieth anniversary of the Arecibo Message approaches researchers at the FAST radio telescope and affiliates at SETI and METI (Messaging Extraterrestrial Intelligence because no one wants to answer their phone apparently) have devised a new bit-mapped series of missives to put out to the Cosmos. The sample image illustrates prime numbers and binary and decimal notation and is one of several (whilst debate continues if it is wise to advertise our presence and level of technologic competence) to be bundled along with the components of DNA, particle physics and human physiology, like this iconic message in a bottle.
