der Storch ist der *inoffzielle Wappenvogel* des Elsaß --- lange Zeit war er vor dem Aussterben bedroht --- jetzt sieht man ihn wieder fast in jedem kleinen Winzerort ---
noch am 10. Oktober 2008 hörte ich einen Weißstorch auf dem Dach eines Hauses neben der Kirche in Eguisheim *klappern*.

These cosmic ribbons of gas have been left behind by a titanic stellar explosion called a supernova. DEM L249 is thought to be the remnant of a Type 1a supernova, the death of a white dwarf star. White dwarf stars are usually stable, but in a binary system ― two stars orbiting each other ― a white dwarf can gravitationally pull so much matter from its companion that it reaches critical mass and explodes.
DEM L249, located in the Large Magellanic Cloud, is an unusual supernova remnant. Astronomers using NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton found its gas was hotter and shone brighter in the x-rays than the remnant of a typical Type 1a supernova. Astronomers suspect DEM L249’s white dwarf star was more massive than expected ― heavier stars expel more gas ― which also means it would have died earlier in its lifecycle.
Hubble took this image while searching for surviving companions of white dwarf stars that went supernova in the Large Magellanic Cloud.

This is a version of the ESA logo like no other: seen through a microscope it measures just over 17 thousandths of a millimetre across, about half the diameter of the average human skin cell.
The logo was carved out of a piece of nickel-based space-grade alloy Inconel using Xenon atoms shot from a plasma ion beam.
While the logo measures 17.43 micrometres (thousandths of a millimetre) in length it is just 700 nanometres (millionths of a millimetre) deep. Click here for an angled view.
“The logo was blasted out of a polished Inconel surface,” explains ESA Young Graduate Trainee Felix Schmidt, serving in ESA’s Materials and Electrical Components Laboratory.
“We created it as practice, in preparation for a project on modelling micromechanical testing. Achieving accurate cuts on a given material is tricky, with many parameters needing to be optimised to get the correct size and depth of the geometry, but this logo shows the kind of accuracy we can reach.”
To get an idea of its actual size, see the logo beside a human hair in this microscopic view – created using stacks of visible light microscope images to achieve the depth of field to get both objects in focus at once.
Felix adds: “Next the plan is to cut out a pillar of metal, then crush it using a nano-indenter, having meanwhile created a high-fidelity ‘digital twin’ of the pillar to accurately model how it behaves as force is exerted on it.”
ESA is already active at creating ‘digital twins’ of space systems at higher scales, explains engineer Michael Mallon, working on digital spacecraft design and verification, “but our aim here is to demonstrate a predictive capability right down to the meso-scale, the next level up from atoms.”

The High Resolution Stereo Camera on board ESA’s Mars Express snapped a view of a curious cloud formation that appears regularly in the vicinity of the Arsia Mons volcano.
This water ice cloud, which arises as the volcano slope interacts with the air flow, can be seen as the long white feature extending to the lower right of the volcano. The cloud, which measures 915 km in this view, also casts a shadow on the surface. This image was taken on 21 September 2018 from an altitude of about 6930 km. North is up.

At the invitation of ESA Director General Josef Aschbacher, NASA Administrator Bill Nelson attended the ESA Council at ESA’s establishment ESTEC in the Netherlands on 15 June 2022.
ESA is currently working with NASA on many areas, from science such as the James Webb Space Telescope to exploration such as Mars Sample Return, Artemis and the International Space Station, to Earth observation.
At the ESA Council, a framework agreement between ESA and NASA for a strategic partnership in Earth System Science was signed, as well as a memorandum of understanding between ESA and NASA on the Lunar Pathfinder mission.

Technology image of the week:
A decade ago, as Europe’s Columbus laboratory module was attached to the International Space Station for microgravity research, ESA’s Large Diameter Centrifuge began offering lengthy experiments in hypergravity.
The principle is simple: the 8 m-diameter four-arm centrifuge is set spinning at up to 67 revs per minute, creating up to 20 times normal Earth gravity for weeks or even months at a time.
As part of ESA’s Life and Physical Sciences Instrumentation Laboratory at the Agency’s technical centre in the Netherlands, the centrifuge’s development was supported by the Dutch government and its use is encouraged by the European Low Gravity Research Association.
For the last decade it has been a place of pilgrimage for researchers, including student experimenters on regular Spin Your Thesis campaigns.
Tomorrow sees a celebration of the centrifuge’s first decade, giving its team the opportunity to hear from their users about desired upgrades and new research ideas.

The European Space Agency (ESA) is expanding its deep space communication capabilities with the construction of a new 35-metre deep space antenna – the fourth of its kind. It will be joining the existing one (on the left-hand side) at New Norcia station, Australia, to help meet the Agency's fast increasing data download needs.
When the new deep space antenna enters service in 2026, it will support ESA’s current flagship missions flown as part of the Agency's scientific, exploration and space safety fleets, including Juice, Solar Orbiter, BepiColombo, Mars Express, Euclid, ExoMars Trace Gas Orbiter and Hera, and later upcoming missions including Plato, Envision, and Vigil.
Learn more about our new antenna.

¿Sabías que la luz que emiten aquellos cuerpos celestes, tarda cuatro años en llegar a la tierra? Bueno quizás la misma luz que sale de ellas ahora te encontrará en otro lugar, con otras personas. O quizás con esas que a pesar de lo que demore en percibir su luminosidad, siempre estarán allí para ti.
A veces hay noches oscuras, pero sabes que esa luz llegará.

Blepharocalyx salicifolius (Kunth) O. Berg
= Blepharocalyx tweediei (Hook. & Arn.) Berg = Blepharocalyx gigantea Lillo
Familia: Myrtaceae (Myrtáceas = Mirtáceas)
Se lo encuentra en selvas climáxicas y en galería de las provincias argentinas de: Corrientes, Jujuy, Misiones, Salta y Tucumán, Entre Ríos, Santa Fe Buenos Aires y Catamarca.
También vegeta en todo el sur del Brasil; buena parte del centro y este del Paraguay; todo el Uruguay; y en buena parte de Bolivia.
La encontramos desde el nivel del mar hasta los 1500 metros de altitud.
El follaje es persistente, color verde brillante, que desde lejos parece gris plateado. Tiene hojas simples, opuestas, lanceoladas, 3,5-5,5 cm de largo.
Ápice acuminado o apiculado, de bordes íntegros, y más claras en el envés.
El ejemplar de la fotografía nos muestra las características de la población de esta especie presente en la región del nordeste argentino y sectores aledaños de sus vecinos países.
Hasta hace pocos años se la consideraba una especie aparte (B. tweediei) .
Llega a tener 7 metros de altura y tronco grueso, oscuro, con corteza finamente agrietada, de unos 50 cm de diámetro, poseyendo una madera muy dura, los tallos de sus ramas son rectos, las flores blanquecinas, de 1 cm de diámetro, a modos de ramilletes se presentan en inflorescencias di o tri floras, 4 pétalos, 4 sépalos, y numerosos estambres.
Florece en primavera.
Frutos bayas redondas, pequeñas de 5 mm de diámetro, con cubierta de color marrón oscuro con tonalidades rojizas, éstos de sabor amargo, recuerdan a los del café, se les da principalmente un uso medicinal.
La maduración de los frutos es gradual, observándose frutos que van del amarillo al rojo-púrpura al mismo tiempo.
Presentan cuatro semillas en su interior.
La madera es indiferenciada entre albura y duramen, color castaño claro, tonos grises, anillos poco demarcados, textura muy fina y grano oblícuo, resistente, de buena calidad, dura y pesada.
La población de esta especie presente en la selva de la yunga del noroeste argentino y sur de Bolivia hasta hace pocos años se la consideraba una especie aparte (B. gigantea).
En esa región alcanzan los 25 metros de altura.
Increiblemente, los científicos recientemente, primero las separaron a ambas solo como variedades de una misma especie, pero luego ni siquiera han mantenido este nivel de separación entre ellas, asignando todas las distintas poblaciones a un mismo taxa muy variable; a pesar de que los notables contrastes de tamaño máximo entre ellas se mantienen aún al ser cultivadas juntas.
En nuestra región vive otra especie de este mismo género: Blepharocalyx cruckshanksii (Hook. & Arn.) Nied. , que es un árbol endémico de Chile, en la cordillera de la Costa desde las regiones Metropolitana de Santiago y quinta, hasta la décima, y desde el nivel del mar hasta unos 200 metros de altitud.
