Moon & Jupiter in the Morning Sky

This morning and also tomorrow morning, the Moon and Jupiter can be seen at the Southern horizon. The Moon is currently 71% illuminated.

Earliest stars born 180 million years after the Universe began.

After 12 years of experimental effort, a team of scientists, led by Arizona State University School of Earth and Space Exploration astronomer Judd Bowman, has detected indications of the earliest stars in the universe. Using radio signals, the detection provides the first evidence for the oldest ancestors in our cosmic family tree, born a mere 180 million years after the universe began.

An observation profile centred around 78Mhz in the sky-averaged spectrum was discovered. “What’s happening in this period is that some of the radiation from the very first stars is starting to allow hydrogen to be seen," said Rogers. "It’s causing hydrogen to start absorbing the background radiation, so you start seeing it in silhouette, at particular radio frequencies. This is the first real signal that stars are starting to form, and starting to affect the medium around them.”

SIDC Series on Lectures on Solar Physics Basics

Lectures 8 & 9 are now available on the Youtube channel from the Royal Observatory of Belgium. See this link here.

The lectures are part of the SIDC series on Solar Physics Basics which I really recommend listening too.

Govert Schilling's Lecture on the Mysterious Universe

Selfie with Govert Schilling

On the evening of March 1, I attended the lecture of The Mysterious Universe by the well know Dutch science journalist Govert Schilling. This happening was organized as part of the Studium Generale lectures at the University of Maastricht.

In the first part a brief overview was given on where are we located (Space), when did this al start (Time) and explaining the relation between our location and time (Space-Time relation). 

The second part covered 9 unsolved mysteries :

     1) How did our Moon originate?

     2) Where is Planet 9?

     3) How unique is Life? 

     4) What are Cosmic Radio Bursts?

     5) What's happening inside a Black Hole?

     6) How did the Baby Universe look like?

     7) What is Dark Matter?

     8) What is Dark Energy?

     9) How unique is our Universe?

Time was flying by and enjoyed listening to the enthusiastic Govert Schilling.
