This video zooms into the Milky Way to the position of the young Sun-like star HD 114082 with an exoplanet and a debris disk. After arriving at the site, we see the orbit of the exoplanet HD 114082 b and the transit signal measured by the spacecraft TESS.
Olga Zakhozhay presents the RV SPY observing program and reports on the discovery of the youngest exoplanet yet known to have mass and size. The talk was a contribution to the "Life In The Universe" conference in Sofia, Bulgaria in October 2022.
The video shows a reconstruction of the distribution of gas around low-redshift, Milky-Way-sized galaxies. The reconstruction is based on a new photoionization modeling method for CGM absorption lines surveys developed by Stern et al. and applied to the COS-Halos survey.
This video zooms into the Milky Way at the position of the stellar black hole “Gaia BH1”, which is currently the closest black hole to Earth. After arriving at this location, we see the orbit of a sun-like star around Gaia BH1.
In this talk, Thomas Henning explains the findings on biochemistry that led to the origin of life on Earth and possibly on other celestial bodies. The talk was a contribution to the conference “Life In The Universe” in Sofia, Bulgaria in October 2022.
On 25 October 2022, a partial lunar eclipse will take place at midday, during which between 15 and 35% of the Sun will be eclipsed in the German-speaking countries. This is an excellent opportunity to take a look at the formation and course of solar and lunar eclipses in advance.
The legendary Hubble Ultra-Deep Field is the sky field for which the best observations exist in many wavelengths. Until now, it has mainly been used to study the stars in high-redshift galaxies. New observations with ALMA now make it possible to also observe the molecular gas that is needed for future star formation. Taken together, the data from…
According to a widespread idea, the Universe is infinitely large. However, this model cannot really be rigorously verified. The lecture will convey the state of knowledge of astronomy on this topic and discuss in particular how large the observable range of the accelerated expanding Universe is in principle. The sophisticated methods astronomers…
