Red planet robots: the quest for life on Mars
Natural Sciences (Astrophysics and Astrononmy)
Date of upload:

Caption:
Whether there was life on Mars at some point in the distant past remains a mystery for scientists. Many discoveries have been made in the last 10 years that have allowed them to shed some light on this question; for instance, we know for a fact that there was water on the Red Planet for millions of years!

Investigating small solar flares with NuSTAR | Kristopher Cooper
Natural Sciences (Astrophysics and Astrononmy)
Date of upload:
20.05.2021
Caption:
Small, highly frequent flares are thought to contribute to heating the Sun’s atmosphere, particularly in active regions. This impulsive energy release would heat plasma >5 MK and accelerate electrons, producing weak thermal and non-thermal signatures that could be observed by a very sensitive X-ray telescope. No such solar telescope exists currently so we use the Nuclear Spectroscopic Telescope Array (NuSTAR), an astrophysical X-ray telescope, with focusing optics imaging spectroscopy providing a unique sensitivity for observing the Sun above 2.5 keV. In this seminar, I will present an overview of the discoveries from NuSTAR solar observations where decreasing solar activity between cycle 24 and 25 has allowed GOES sub-A class microflares to be observed regularly within, and small brighten

Caption:
The sequence shows the evolution of dynamic structures resembling tornadoes in the solar atmosphere. The blue and green color scheme shows the vorticity in the solar atmosphere in the regions where solar tornadoes appear. The reddish contour shows the dynamic evolution of the $\beta=1$ layer, the gray contour displays the $\tau=1$ layer.
