Najnudniejsze z ciekawych zdjęć

Fotografia czarnej dziury z galaktyki M87 trafiła dokładnie w symulacje. Teleskop wielkości Ziemi dał podobny efekt co obliczenia kilku fizyków wielkości Homo sapiens. Nuda, można się rozejść.

Zanim rozejdziemy się w swoje strony, warto zajrzeć za kotarę – dlaczego jeden

Co skrywają internetowe zbiórki na chorych?

Treść zbiórek internetowych, szczególnie w temacie chorób, to absolutny temat tabu w internecie. Nie można o tym pisać i już. Kto podejmuje temat, ten jest człowiekiem bez serca, który cyt. „nie powinien się interesować”. W cieniu tego milczenia rosną potwory,

Recenzja studiów na kierunku biologia – Uniwersytet im. Adama Mickiewicza (UAM) / + o stanie polskich uniwersytetów

Kilka lat temu szukałem w internecie recenzji polskich uczelni i kierunków, by wesprzeć decyzję o wyborze studiów. Dziś, już po drugiej stronie lustra dorzucam swoją opinię na temat wydziału biologii Uniwersytetu im. Adama Mickiewicza.

Dlaczego tak mało wiemy o tym, czy Homo sapiens może zajść w ciążę poza Ziemią?

Myślę, że istnieje istotny, humanitarny argument, z powodu którego powinniśmy żyć na wielu planetach. Musimy zabezpieczyć istnienie ludzkości w razie katastrofy.

najnowsze zdjęcia europejskiej agencji kosmicznej – od 2012 roku Polska jest jej ważną częścią

  • 🐈 or 🦇 ❓ From a distance of five million kilometres to within 20 metres, our Rosetta spacecraft captured images of Comet 67P/Churyumov-Gerasimenko from all angles. Between the first and the last images lies one of humanity’s greatest space adventures to rendezvous with and follow a comet as it orbited the Sun, and deploy a lander to its surface. Go to our @instagram Story to learn more about this image and Rosetta's mission. 📸 @europeanspaceagency / Rosetta / MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA (@creative commons, CC BY-SA 4.0)
  • Were you hunting for eggs this weekend? 🥚 ⠀⠀⠀ This remarkable video captured by the Deimos Sky Survey in Spain doesn't show an broken egg but the stream of newly-made debris objects as they rush across the sky. ⠀⠀⠀ In the clip, a number of small point-like fragments can be seen spread horizontally across frame. As the observatory moves with the debris objects, the background stars are seen as white streaks. ⠀⠀⠀ The remnant piece is clearly visible as the largest and brightest point at the centre of about 40-60 smaller pieces, many larger than 30 cm in size, and has been traced back to the upper stage of a rocket launched in September 2009. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 Deimos Sky Survey #ESA #SpaceDebris #Debis
  • Because every day is #EarthDay 🌎🌍🌏 #Repost @esa_earth ・・・ The Virunga Mountains, home of the endangered Mountain Gorilla 🦍 Today, to celebrate Earth Day, the Copernicus Sentinel-2 satellite takes over the Virunga Mountains, a chain of volcanoes that straddle the borders of the Democratic Republic of the Congo, Rwanda, and Uganda. They are home to the critically endangered Mountain Gorilla, of which there are fewer than 900 left in the world. A series of national parks has been established across the mountain range to protect what is considered one of Africa’s most biologically diverse regions. • 📸 contains modified @copernicus_eu Sentinel data (2016), processed by @europeanspaceagency , @creativecommons CC BY-SA 3.0 IGO
  • Hubble Time! 🌌⠀⠀⠀ ⠀⠀⠀ The richly textured spiral galaxy NGC 2082 is found about 60 million light-years away in the constellation of Dorado (the Swordfish), deep in the southern sky. As seen here in a very detailed image from the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope, filaments of dark dust splay across NGC 2082’s luminous curved arms and dense central bulge of stars. Hubble’s sharp vision also reveals many of the individual bright blue stars dotting the galaxy’s rather ragged spiral arms as well as many much more distant galaxies in the background. ⠀⠀⠀ This galaxy is faintly visible in backyard telescopes and was first recorded by Sir John Herschel during his visit to the Cape of Good Hope in South Africa in the 1830s. NGC 2082 was also the host of a bright supernova that was spotted by the great visual supernova discoverer Rev R. Evans back in 1992. ⠀⠀⠀ 📸 @europeanspaceagency, @hubbleesa & @NASA, @creativecommons CC BY 4.0 ⠀⠀⠀ #ESA #EuropeanSpaceAgency #HubbleSpaceTelescope
  • You never looked better! 📡 ⠀⠀⠀ Our 35-metre radio antenna in Malargüe, Argentina, has had a major refurbishment. Extenstive modifications made will now allow the ESTRACK network to support future mission like Euclid, launching in 2022, and to transfer data at much higher rates. Upgrades to the Malargüe station, and similar upgrades carried out in the Cebreros station located in Spain in 2017, make a big difference to deep space missions. ⠀⠀⠀ The refurbishment of Cebreros and Malargue stations, will allow our deep space antennas to receive broadband signals at 26GHz as well as the conventional X-band frequency. ⠀⠀⠀ Go to our @instagram Story to learn more ⠀⠀⠀ 📸 @europeanspaceagency / Filippo Concaro
  • Back to the water! 🦀 ⠀⠀⠀ In the absolute darkness of caves, rare creatures have returned to living in water to survive. Astronauts looking for life in the underworld during the CAVES training courses discovered a new species of crustaceans that have completed an evolutionary full circle – from water to land, and back to water again. ⠀⠀⠀ Just under one centimetre long, these animals belong to the suborder of terrestrial isopods, commonly known as woodlice. ⠀⠀⠀ Most crustaceans such as shrimps and lobsters live in water while woodlice are the only group that has fully adapted to life on land. ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 @europeanspaceagency – M.

  • Who doesn't love globular clusters?⠀😍⠀⠀ ⠀⠀⠀ The subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of globular clusters. ⠀⠀⠀ Containing an incredible half a million stars, this eight-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered. However, what makes Messier 3 extra special is its unusually large population of variable stars — stars that fluctuate in brightness over time. New variable stars continue to be discovered in this sparkling stellar nest to this day, but so far we know of 274, the highest number found in any globular cluster by far. At least 170 of these are of a special variety called RR Lyrae variables, which pulse with a period directly related to their intrinsic brightness. If astronomers know how bright a star truly is based on its mass and classification, and they know how bright it appears to be from our viewpoint here on Earth, they can thus work out its distance from us. For this reason, RR Lyrae stars are known as standard candles — objects of known luminosity whose distance and position can be used to help us understand more about vast celestial distances and the scale of the cosmos. ⠀⠀⠀⠀ ⠀⠀⠀ Go to our @instagram Story to learn more. ⠀⠀⠀ 📸 @europeanspaceagency / @hubbleesa & @NASA, G.
