An Analysis of Interplanetary Solar Radio Emissions Associated with a Coronal Mass Ejection by V. Krupar et al.*

by CESRA in Solar Radio Science

Type II and type III bursts are generated, via the plasma emission mechanism, when beams of suprathermal electrons interact with the ambient plasma generating radio emissions at the plasma frequency fp (the fundamental emission) or at its second harmonic 2fp (the harmonic emission) [see also previous CESRA highlights here and [...]...

High resolution observations of radio noise storms in the solar corona

by Prasad Subramanian and Claude Mercier in Solar Radio Science

The solar corona is a well known site for particle acceleration – examples range from spectacular large flares to the hard-to-observe nanoflares that are now a leading candidate for coronal heating.... Read more »

The Genesis Project: New life on exoplanets

by Dr. Jekyll in Lunatic Laboratories

Can life be brought to celestial bodies outside our solar system, which are not permanently inhabitable? A new essay that has been published is trying to deal with this question. Over the last several years, the search for exoplanets has shown that very different types exist leading to new questions and a variety of possible answers.

Bright 30 THz impulsive solar bursts by Pierre Kaufmann et al.*

by CESRA in Solar Radio Science

Impulsive 30 THz continuum bursts have been recently observed in solar flares, utilizing small telescopes with a unique and relatively simple optical setup concept (Kaufmann et al. 2015). The most intense burst was observed together with a GOES X2 class event on October 27, 2014, also detected at two sub-THz [...]... Read more »

Particle Acceleration and heating by turbulent reconnection by L. Vlahos, T. Pisokas, H. Isliker, V. Tsiolis and A. Anastasiadis

by CESRA in Solar Radio Science

Fermi (1949) introduced a fundamental stochastic process to solve the problem of particle energization (heating and/or acceleration) in space and astrophysical plasmas. The initial idea of Fermi with randomly moving scatterers (magnetic clouds), was soon replaced with a spectrum of low amplitude (δΒ/Β... Read more »

Space disturbs the heart-related system and increases the chances of death

by Usman Paracha in SayPeople

Main Point:

Deep space missions could increase the chances of cardiovascular diseases, thereby increasing the chances of deaths in astronauts.

Published in:

Scientific Reports

Study Further:

NASA’s Apollo program sent 9 manned missions and 24 astronauts above the low Earth orbit (LEO) during decades of 1960s and 1970s. Those missions also included Apollo 11, which was used to take Neil Armstrong and Buzz Aldrin to the moon. However, it appears that such beyond Earth missions........ Read more »

An equation for life

by gdw in FictionalFieldwork

Water churns. Earth moves. Molecules jostle and chemicals mix. Between heaven and hell, a young planet finds itself in full flux. Developing. Forming. Star stuff rains down and forged elements bubble up. Then it happens. It seems as if it’s just another chemical match-up, another reaction in the vast library of possibilities. But it would […]...

Flipping the Drake Equation for a deep time perspective on the Fermi Paradox

by gdw in FictionalFieldwork

Is anybody out there? Where are all the alien civilizations? Even if (intelligent) life is very unlikely, the sheer size and age of the universe means that even long odds might have produced space faring civilizations. Yet, so far, nada. When people are considering the (im)probability of non-human space travellers, one thing always comes up: […]... Read more »

End of Universe – estimated earliest time

by Usman Paracha in SayPeople

Main Point:

Universe would end earlier than the anticipated time for the Sun to burn completely.

Published in:

arXiv

Study Further:

Scientific observation of the stars and galaxies in our universe are showing that the universe is continuously expanding, and the rate of this expansion is continuously increasing. After looking at this continuous expansion, one of the suggested possibilities for the future is that, the stars would die, everything in the universe will drift out, and t........ Read more »

New model says that the Universe has no start and it existed forever

by Usman Paracha in SayPeople

Main Points:

According to a new model, Big Bang never happened and Universe existed forever without any beginning.

Published in:

Physics Letters B

Study Further:

According to our present knowledge, Universe came into existence about 13.8 billion years ago. Before the existence of Universe, everything was in the form of a tiny point, which is also referred to as singularity. Therefore, it is assumed that everything in the Universe was present in that tiny point at that time. Then a........ Read more »

Earth = combination of two planets (study shows)

by Usman Paracha in SayPeople

Main Point:

Earth is actually a combination of two planets, i.e. Earth and Theia, a planet thought to be about the size of Mars.

Published in:

Science

Study Further:

Researchers from University of California Los Angeles (UCLA) have recently reported that there was a “violent, head-on collision” of Earth and Theia, which is thought to be an ancient planet having the approximate size of Mars or according to some it was about Earth’s size, about 4.5 billion years ag........

New reports for a giant planet in the Solar System

by Usman Paracha in SayPeople

Main Point:

Our Solar System has ninth planet in the outer spaces as evidenced by researchers.

Published in:

The Astronomical Journal

Study Further:

Researchers have recently reported that they have found the best known evidence for the existence of ninth planet, referred to as Planet X or Planet Nine, at the outer limits of our Solar System. However, it has been noted that there are no direct evidences for the presence of ninth planet. Researchers have based their argument about ........ Read more »

‘Space Warps’ and other citizen science projects reap major dividends for astrophysics

by Dr. Jekyll in Lunatic Laboratories

Thanks to the Internet, amateur volunteers known as "citizen scientists" can readily donate their time and effort to science--in fields ranging from medicine to zoology to astrophysics. The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be.

Beam me up! Teleporting the memory of an organism

by Dr. Jekyll in Lunatic Laboratories

In "Star Trek", a transporter can teleport a person from one location to a remote location without actually making the journey along the way. Such a transporter has fascinated many people. Quantum teleportation shares several features of the transporter and is one of the most important protocols in quantum information.... Read more »
