Gaia on 3sat: TV-Report with Stefan Jordan

TV broadcaster "3sat" has released an interesting TV-report on the Gaia mission. Stefan Jordan explains some highlight of the first science that has been performed with the Gaia Data Release 2, published on April 25, 2018. (25.2.2019)

Tidal Tails – The Beginning Of The End Of An Open Star Cluster

Heidelberg researchers verify this phenomenon using Gaia data from the Hyades. (15.2.2019)

Open star clusters live longer than previously assumed

Heidelberg researchers used simulations to investigate how the formation conditions of open star clusters affect their long-term evolution. The simulations indicate that they exist 100 times longer than previously assumed. (14.01.2019)

ALMA provides unprecedented views of the birth of planets

The first survey of protoplanetary disks using the Atacama Large Millimeter/Submillimeter Array (ALMA) revealed unknown structures which likely are the sites for planets to be formed. ZAH is one of the leading partners of the campaign. (12.12.2018)
