The planets will move closer and closer in the night sky until March 1.

NASA aims to send a lander that can survive Venus’ crushing atmosphere
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.
Now, NASA aims to build a lander called LLISSE, that can withstand those conditions and beam a wealth of data about our nearest planetary neighbor back to Earth.

Scientists make a rare find: A Solar system with three Super-Earths
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.
‘Hidden’ planet at edge of our solar system could be five times the size of Earth
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.
