On October 7, 2023, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired a true-color image of “The Eye of the Sahara”.

Although it looks like it could be an impact crater, it actually formed when a volcanic dome hardened and then gradually eroded, slowly exposing the ringed rock layers. The result is an onion-like formation, with ridges formed of weather-resistant rocks while less-resistant rock forms valleys between the ridges. Some of the igneous rocks found within the structure have been dated as having cooled between 94 and 104 million years ago.

Ash Cloud This satellite image from the MODIS instrument on NASA’s Terra satellite captures an eruption of the volcano Nishinoshima, on a tiny, remote island almost 1000 kilometers away from Japan. The volcano first awakened in 2013 and eventually grew large enough to consume a nearby island from a previous volcanic event. Although it was quiet for a few years after this burst of activity, it has been active again since last December and particularly vigorous in its eruptions over the last month or so.

On any given day, there are often a dozen or more volcanoes actively erupting around the world. This one is so far away from everything that there’s little reason to hear about it, as is the case with many eruptions around the world. -JBB Image credit: https://flic.kr/p/2jkpjgj

MENANG GAYA, OTAK NOL

Intinya jangan pernah berhenti belajar. Tidak masalah tidak mengikuti GAYA, yang penting otakmu KAYA. Biarlah dibilang kampungan asal otakmu kelas INTERNASIONAL. Kalau otak sudah dipenuhi dengan berbagai ilmu dan pengalaman yang bermanfaat, insyaAllah gak akan mati GAYA.

Diriwayatkan oleh H.R. Bukhari: "Barang siapa ingin memperoleh kebahagiaan hidup di dunia harus dengan ilmu dan barang siapa ingin memperoleh kebahagiaan akhirat harus dengan ilmu dan barang siapa ingin memperoleh kebahagiaan di dunia dan akhirat harus dengan ilmu".

The Río de la Plata Estuary, between the countries of Uruguay (north) and Argentina (south), where the Uruguay and Paraná Rivers meet (August 21st, 2007).  This photography was taken by MODIS on NASA's Terra satellite.

Each year, a large amount of sediment is carried into the estuary, where the muddy waters are stirred up by the winds and the tides.  The red dots are the locations of active fires.

An Intersection of Land, Ice, Sea and Clouds by NASA's Marshall Space Flight Center Via Flickr: As sea ice at far northern latitudes approached its annual maximum extent, the Terra satellite captured this natural-color image of sea ice and clouds off of Canada’s Newfoundland and Labrador province. Though sea ice has been significantly below normal extent and thickness across much of the Arctic, the ice in the Labrador Sea has been relatively close to normal. In this image, acquired on Feb. 18, 2018, the coastline, the sea ice edge, and offshore clouds all present a clear edge to distinguish one from the next. Ice hugs the coast, where it receives the full chilling effect of offshore winds, and the water is shallower and fresher than in the open sea. The swirl patterns on the eastern edges reveal areas where ice is new and has not yet consolidated into a solid sheet, so it is more susceptible to stirring by winds and by ocean eddies.
