Enhanced image captured by NASA’s Perseverance rover on Sol 1974 (September 9, 2026, 13:44:08 UTC) using the Left Mastcam-Z Camera. The image showcases a close-up view of the Martian surface in Jezero Crater, featuring a prominent, angular rock with a weathered, dust-covered surface surrounded by fine-grained sand and scattered pebbles. The intricate textures and sharp details of the rock highlight the geological diversity and the dynamic, wind-shaped landscape of Mars. Image Credit: NASA/JPL-Caltech/ASU/Jackie Branc.

Mars Perseverance Rover Outside Jezero Crater Sol 1972 (6th September, 2026) Some eye-catching 'speckly' rocks at first glance and the closer you view them the more interesting they become Captured by Mastcam-Z (L) S/D: 91/806 CC BY-NC-SA 4.0 Credits: NASA/JPL-Caltech/ASU/MSSS/Martian-Observer
A general context view of the rocky dust covered terrain - there are many scattered lumps of 'speckled' rock in various states of partial erosion plus some dark rocks showing no speckles at all.A very eroded example of a 'speckled' rock which is absolutely riddled with tiny holes and cavities.A much larger example of 'speckly' rock that has had a circular abrasion ground into it. The dark colour is apparently remnants of a resilient purplish coating, the white rock underneath is highly reflective and looks mineral crystalline, like milky quartz.

A dark cloud by JWST🔭, NIRCam, name and credits quoted. Alt-Text by chatGPT captured the fact that "reddish-orange sources and patches are embedded within". The stars are redder because the dark dust serves as a filter, allowing longer wavelengths through.
chatGPT: dark molecular cloud G28.333+0.063, set against an exceptionally dense stellar field in the Milky Way. Thousands of stars fill the image, ranging from tiny points to brilliant stars with prominent diffraction spikes. Much of the cloud is visible as a broad, dark, relatively star-poor region toward the center, where dense dust obscures the stars behind it. Numerous faint reddish-orange sources and patches are embedded within or seen through the cloud, while a brighter, compact region of orange and red nebulosity appears on the right side, associated with active star formation. Wisps of diffuse emission and darker dust structures extend across the lower part of the image. The striking contrast between the crowded background and the dark obscuring cloud reveals how dense interstellar dust blocks the light of the Galactic stellar population behind it

🔥 Wo brennt es gerade und wie breitet sich das #Feuer aus? Das Fire Monitoring System des ZKI am DLR liefert nahezu in Echtzeit Antworten. Mithilfe von Satellitendaten kartiert es weltweit Brandflächen und zeigt deren Entwicklung, Brandschwere und betroffene Fläche: services.zki.dlr.de/fire/
Waldbrände, eine Gefahr für Mensch, Natur und Wirtschaft

Werden Waldbrände früh genug entdeckt, lassen sich die Schäden meist begrenzen. Unter anderem mit luft- und satellitengestützter Früherkennung arbeitet das DLR an innovativen, modernen und robusten Methoden und Tools, um Einsatzkräfte in ihrem Kampf gegen die Flammen mit aktuellen Informationen zu versorgen. Auf der Grundlage verlässlicher Daten können sie so schnell die richtigen Entscheidungen treffen.

Credit: Zirocool – stock.adobe.comWaldbrände in Portugal

Wenn man dem Satellitenbild ein Bild im Infrarotspektrum überlagert, kann man (hellrot) auch diejenigen Feuer erkennen, die nur wenig Rauch erzeugen.

Credit: DLR (CC BY-NC-ND 3.0)Das "ZKI Fire Monitoring System" des DLR liefert aktuelle Waldbrandinformationen für Europa der letzten 31 Tage. Mit dem Ziel, verbrannte Flächen und deren räumliche Entwicklung nahezu in Echtzeit zu überwachen, wurde ein vollautomatisierter Ansatz entwickelt (Nolde et al. 2020, Link zur Publikation https://doi.org/10.3390/rs1213216 2) und in einer operativen Verarbeitungskette umgesetzt. Um mehrere Aktualisierungen pro Tag zu erreichen, werden Satellitendaten mittlerer Auflösung verwendet. Das Informationssystem ermöglicht eine interaktive Analyse aktueller Waldbrände in jedem von einem Benutzer definierten Interessengebiet.

Die täglichen Produkte zeigen die Grenzen der verbrannten Gebiete, Minuten nachdem Satellitenbilder verfügbar sind. Für MODIS erfolgt der Datenempfang über die DLR-Bodenstationen in Neustrelitz und Oberpfaffenhofen (Deutschland) mittels Direktübertragung bei jeder Satellitenüberführung. Für Copernicus Sentinel-3-Daten stützen wir uns auf den Datenverteilungsmechanismus des Sentinel Open Access Hub der Europäischen Weltraumorganisation und das Copernicus Data Integration and Analysis System (DIAS).

Die Produkte der verbrannten Fläche werden iterativ und automatisch über einen Zeitraum von 10 Tagen aktualisiert, sobald neue Satellitendaten verfügbar sind. Dies ermöglicht eine kontinuierliche Verbesserung der abgeleiteten Brandperimeter, indem der Einfluss von Störfaktoren wie Wolkenbedeckung, Rauchfahnen und Schatten minimiert wird.

Neben dem Brandflächenumfang fließen weitere Attribute wie die Brandschwere, die betroffene Fläche sowie die genauen Erkennungszeiten in die Daten ein. Es ist daher möglich, die Entwicklung jedes verbrannten Bereichs in Raum und Zeit zu verfolgen.Das DLR verknüpft Technologien aus Raumfahrt, Luftfahrt, KI und Sicherheit zu den verschiedensten Aspekten einer modernen Waldbrandüberwachung – von der globalen Detektion über Drohnenschwärme bis zur Echtzeitunterstützung mit Daten und Karten aus dem All für eine effektive, effiziente und sichere taktische Einsatzplanung vor Ort.

🧵(1/2) IC 1396 is an emission nebulae, located in the constellation Cepheus about 2,400 light years away from Earth. Reprocessed 26-08-01, shot taken on 25-09-19 from my backyard. 🔭 William Optics Red Cat 61 📷 ZWO ASI 2600 + L-Extreme Exposure: 3h45 #Astrophotography #Space #DeepSpace #Astronomy
Image of The Elephant's Trunk Nebula (IC 1396A) is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.[1] The nebula is a dark, dense globule that gets its name from its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive multiple star (HD 206267) that is just to the east of the Elephant's Trunk Nebula . The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
