In a landmark first, scientists have grown plants in lunar soil using samples collected during the Apollo missions to the moon. This is the first time plants have been sprouted and grown on Earth in soil from another celestial body.

Welcome to our 42nd webinar on "Hunting for ghost particles - Neutrino Astronomy at the South Pole ".
Neutrinos are the most elusive elementary particles. They have a tiny mass and do not carry electric charge. Those tiny particles are created in nuclear fusion and fission.
Their unique properties allow neutrinos to escape even from the densest environments, from where light cannot reach us - for example the center of the Sun. Therefore neutrinos carry invaluable information, which is hidden to classical astronomy. At the same time those properties make neutrinos very hard to detect. Giant detector volumes are required to catch those rare cases where a neutrino interacts with an atomic nucleus and leaves a visible trace.
The IceCube neutrino observatory located in the clear glacial ice of the South Pole is the largest currently operating neutrino telescope with a volume of one cubic kilometer (equivalent to the volume of 400.000 olympic pools).
This talk will focus on high-energy neutrinos, which are produced in the most violent sources in the Universe, for example super-massive black holes that swallow an entire star (so-called tidal disruption events). Our guest will highlight what we can learn from neutrinos in addition to observations in different wavelengths.

Welcome to our 41st webinar on ''THE ACCELERATING EXPANDING UNIVERSE: DARK MATTER, DARK ENERGY, AND EINSTEIN'S COSMOLOGICAL CONSTANT".
Dark energy is the leading candidate for the mechanism that is responsible for causing the cosmological expansion to accelerate. Professor Bharat Ratra will describe the astronomical data which persuade cosmologists that (as yet undetected) dark energy and dark matter are by far the main components of the energy budget of the universe at the present time. He will review how these observations have led to the development of a quantitative "standard" model of cosmology that describes the evolution of the universe from an early epoch of inflation to the complex hierarchy of structure seen today. He will also discuss the basic physics, and the history of ideas, on which this model is based.

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi, talk to their friends about math, and eat pie.
Pi has been calculated to over 50 trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.
Happy Pi day!
Albert Einstein, a German genius, gave the world some groundbreaking theories. The prominent mathematician and physicist, Albert Einstein is best known for his mass-energy equivalence formula E = mc2 and "general theory of relativity". Today, on March 14, the world is celebrating Albert Einstein's 143th birthday. He is recipient of Nobel Prize for Physics for his explanation of the photoelectric effect. Known for his intellectual achievements and originality, he is one of the most celebrated scientist.
Happy birthday genius!
