NASA aims to send a lander that can survive Venus’ crushing atmosphere

Posted by in category: space

Firstly, the space agency must develop a battery that can withstand Venus’ hellish conditions.

You may be surprised to learn that humans have sent several landers to Venus’ surface. The Soviet Venera missions, for example, transmitted the first-ever image from another planet on October 20, 1975, after sending its Venera 9 lander to the surface of Venus.

That mission lasted less than two hours on the planet’s surface due to the immense atmospheric pressure and scorching temperatures on Earth’s so-called evil twin.

Scientists make a rare find: A Solar system with three Super-Earths

Posted by in categories: physics, space

Three Super-Earths and two Super-Mercuries, a type of planet that is extraordinarily rare and distinct, haʋe Ƅeen found in a star systeм Ƅy astronoмers. Super-Mercuries are so uncoммon—only eight haʋe Ƅeen found so far—that they are extreмely rare.

ESPRESSO’s spectrograph detected two ‘super-Mercury’ worlds in the star systeм HD 23472. Astronoмers haʋe discoʋered that these planets are extreмely rare. This study, puƄlished in Astronoмy &aмp; Astrophysics, looked at how the coмposition of tiny planets ʋaries with planet position, teмperature, and star attriƄutes.

The reason for oƄserʋing this planetary systeм, according to Susana Barros, a researcher at the Institute of Astrophysics e Ciências do Espaço (IA) who led the project, is to characterise the coмposition of sмall planets and to study the transition Ƅetween haʋing an atмosphere and not haʋing an atмosphere.

Arctic and save Greenland’s glaciers.

George Soros proposes geoengineering project to save Greenland’s glaciers.


Less problematic geoengineering already is underway with CO2 direct air capture. But more controversial sunlight blocking is being proposed.

‘Hidden’ planet at edge of our solar system could be five times the size of Earth

Posted by in category: space

A huge planet that has never been seen by astronomers could be lurking, almost invisibly, at the dark edges of our solar system, some scientists believe.

By 1,846, astronomers had pinpointed all the eight main planets – and have since found several other ’dwarf planets’ including Pluto.

But the search goes on for the mysterious ‘ninth planet’ which is thought to sit far beyond Neptune in our solar system, said space expert Sara Webb.

Quantum Telescopes Could Offer Clearer Views of Our Solar System and Beyond

Posted by in categories: particle physics, quantum physics, space

Scientists want to use quantum mechanics to capture higher-resolution images of the night sky.


For the purposes of astronomy, the two beams are collected by two telescopes that are separated by some distance (called baseline interferometry). But despite its effectiveness, classic interferometry is subject to some limitations. Andrei Nomerotski, an astrophysicist with the BNL and a co-author on the paper, explained to Universe Today via email.

“Interferometry is a way to increase the effective aperture of telescopes and to improve the angular resolution or astrometric precision,” he said. “The main difficulty here is to maintain the stability of this optical path to very high precision, which should be much smaller than the photon wavelength, to preserve the photon’s phase. This limits the practical baselines to a few hundred meters.”
