Benjamin died on September 7th, 1936 in Hobart zoo. It is believed that he died out of neglect, as he was locked out of his shelter and was exposed to the searing hot sun and freezing cold night of Tasmania.
The Thylacine was one of the last large marsupials left on Australia (the other being the Kangaroo) after a great extinction event occurred around 40 thousand years ago. This extinction event, caused mainly by the arrival of humans, wiped out 90% of Australia’s terrestrial vertebrates, including the famous Megafauna.
The Thylacine was around 15-30kg (33-66lbs), were carnivorous, and had numerous similarities to other species like dogs, despite not being related and purely by chance, in a phenomenon known as convergent evolution (just like the ability to fly of bats and birds, despite following different evolutionary paths). Not only that, they could open their jaws up to 120 degrees, could hop around on two legs like a kangaroo, and both males and females had pouches.
Lastly in a cruel twist, the Tasmanian government decided to protect the Thylacine - just 59 days before the last one died, in a very notable case case of “Too little too late”. To date, many biologists believe that there are still Thylacine roaming the wild plains of Australia.
The gender divide in science is cultural rather than anything to do with women’s brains and some countries do much better than others, she says.
In astrophysics southern European countries like France, Spain and Italy do much better than northern European countries like Germany and The Netherlands, for instance.
“In all those countries the proportion of women is going up but the pattern has stayed the same, which is interesting,” she says.
“The progress is slow, things are changing gradually.”
Her advice to women in science? “Don’t be daunted, hang in there, work hard, of course, be courageous.”

NASA’s announcement today was awe-inspiring. We’ve compiled the essential info you want to know about this incredible discovery.
OVERVIEW: 7 PLANETS, 3 HABITABLE
Astronomers have found at least seven Earth-sized planets orbiting the same star 40 light-years away, according to a study published Wednesday in the journal Nature.
The seven exoplanets were all found in tight formation around an ultracool dwarf star called TRAPPIST-1. Estimates of their mass also indicate that they are rocky planets, rather than being gaseous like Jupiter. Three planets are in the habitable zone of the star, known as TRAPPIST-1e, f and g, and may even have oceans on the surface.
“I think we’ve made a crucial step towards finding if there is life out there,” said Amaury Triaud, one of the study authors and an astronomer at the University of Cambridge. “I don’t think any time before we had the right planets to discover and find out if there was (life). Here, if life managed to thrive and releases gases similar to what we have on Earth, we will know.”
ONLY 40 LIGHT YEARS AWAY
The system is just 40 light-years away. On a cosmic scale, that’s right next door. Of course, practically speaking, it would still take us hundreds of millions of years to get there with today’s technology – but again, it is notable in that the find speaks volumes about the potential for life-as-we-know-it beyond Earth.
The Hubble Space Telescope is already being used to search for atmospheres around the planets, and Emmanuël Jehin, a scientist who also worked on the research, asserts that future telescopes could allow us to truly see into the heart of this system: “With the upcoming generation of telescopes, such as ESO’s European Extremely Large Telescope and the NASA/ESA/CSA James Webb Space Telescope, we will soon be able to search for water and perhaps even evidence of life on these worlds.”
ALIEN SKIES
In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.
The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes.

yknow black dwarfs,,, do they actually exist and do they actually live longer than the universe,,
Yes. When stars of a certain mass run out of fuel, they expel their outer layers ( a planetary nebula)
What’s left, in the center is a white dwarf. The core of the original star. Can you see it in the center of this planetary nebula? (NGC 7662)
That white dwarf glows only because of heat, it is not actually making any new light. So, that white dwarf will cool down and leave a dark chunk of mass behind
Crab walks around with Jellyfish on its back to protect it from predators
These #jellyfish Cassiopea (upside-down jellyfish) partake in a symbiotic relationship with photosynthetic dinoflagellates and therefore, must lay upside-down in areas with sufficient light penetration to fuel their energy source. Where found, there may be numerous individuals with varying shades of white, blue, green and brown.
Sometimes this jellyfish is picked up by the #crab Dorippe frascone and carried on its back. The crab uses the jellyfish to defend itself against possible predators.
This is a studyblr for everyone have some passion for science, especially astronomy and biology
