#Zomer (Astronomisch) noord / #Winter (Astronomisch) zuid 2025

De zomer is een van de vier seizoenen op Aarde.

Het astronomisch bepaalde begin van de zomer is de zomerzonnewende (rond 21 juni op het noordelijk halfrond en rond 21 december op het zuidelijk halfrond). De zon gaat dan door het zomerpunt, de zon bereikt die dag de hoogste stand boven de horizon en de dag duurt het langst. De zomer eindigt met de herfst-equinox (rond 23 september op het noordelijk halfrond en 20 maart op het zuidelijk halfrond).

Babelsberger Sternennächte : Was uns Doppelsterne über die Rotation verraten | Dr. David Gruner (TV webcast)

Die Babelsberger Sternennächte finden online statt, in der Regel gibt es immer am 3. Donnerstag im Monat einen neuen Vortrag einer Wissenschaftlerin oder eines Wissenschaftlers des AIP, der ab 20 Uhr auf dem YouTube-Kanal von Urknall, Weltall und das Leben ausgestrahlt wird (Playlist).

In einem Doppelsternsystem kreisen zwei Sterne umeinander. Im Vortrag geht es jedoch nicht um die Umlaufbewegung der beiden Sterne umeinander, sondern um ihre jeweils eigene Drehung um sich selbst. Die Eigenrotation verändert sich im Laufe des Lebens eines Sterns und kann zur Bestimmung des Sternalters genutzt werden. Die zwei Sterne eines Doppelsterns sind gemeinsam aus derselben Gaswolke entstanden und daher gleich alt. Der Vortrag beleuchtet, wie diese Gleichaltrigkeit dazu genutzt werden kann, den Zusammenhang zwischen Alter und Rotation von Sternen zu untersuchen.

Day for the Elimination of Sexual Violence in Conflict 2025

The term “conflict-related sexual violence” refers to rape, sexual slavery, forced prostitution, forced pregnancy, forced abortion, enforced sterilization, forced marriage and any other form of sexual violence of comparable gravity perpetrated against women, men, girls or boys that is directly or indirectly linked to a conflict.

The term also encompasses trafficking in persons when committed in situations of conflict for the purpose of sexual violence or exploitation. A consistent concern is that fear and cultural stigma converge to prevent the vast majority of survivors of conflict-related sexual violence from coming forward to report such violence. Practitioners in the field estimate that for each rape reported in connection with a conflict, 10 to 20 cases go undocumented. On 19 June 2015, the United Nations General Assembly (A/RES/69/293) proclaimed 19 June of each year the International Day for the Elimination of Sexual Violence in Conflict, in order to raise awareness of the need to put an end to conflict-related sexual violence, to honour the victims and survivors of sexual violence around the world and to pay tribute to all those who have courageously devoted their lives to and lost their lives in standing up for the eradication of these crimes. The date was chosen to commemorate the adoption on 19 June 2008 of Security Council resolution 1820 (2008), in which the Council condemned sexual violence as a tactic of war and an impediment to peacebuilding. In response to the rise in violent extremism, the Security Council adopted resolution S/RES/2331 (2016), the first to address the nexus between trafficking, sexual violence, terrorism and transnational organized crime. Acknowledging sexual violence as a tactic of terrorism, it further affirmed that victims of trafficking and sexual violence committed by terrorist groups should be eligible for official redress as victims of terrorism.

#Juneteenth 2025

Juneteenth (officially Juneteenth National Independence Day and historically known as Jubilee Day, Black Independence Day, and Emancipation Day) is a federal holiday in the United States (US) commemorating emancipation of enslaved African Americans.

It is also often observed for celebrating African American culture. Originating in Galveston, Texas, it has been celebrated annually on June 19 in various parts of the US since 1866. The day was recognized as a federal holiday on June 17, 2021, when President Biden signed the Juneteenth National Independence Day Act into law. Juneteenth’s commemoration is on the anniversary date of the June 19, 1865, announcement of General Order No. 3 by Union Army general Granger, proclaiming freedom for enslaved people in Texas. President Lincoln‘s Emancipation Proclamation of 1862 had outlawed slavery in Texas and the other states that had rebelled against the Union almost two and a half years earlier. Enforcement of the Proclamation generally relied on the advance of Union troops. Texas, as the most remote of the slave states, had seen an expansion of slavery and had a low presence of Union troops as the American Civil War ended; thus, enforcement there had been slow and inconsistent prior to Granger’s announcement. Although the Emancipation Proclamation declared an end to slavery in the Confederate States, slavery was still legal and practiced in two Union border states – Delaware and Kentucky – until December 6, 1865, when ratification of the Thirteenth Amendment to the Constitution abolished chattel slavery nationwide. Additionally, Indian Territories that had sided with the Confederacy, namely the Choctaw, were the last to release those enslaved, in 1866.

Celebrations date to 1866, at first involving church-centered community gatherings in Texas. It spread across the South and became more commercialized in the 1920s and 1930s, often centering on a food festival. Participants in the Great Migration out of the South carried their celebrations to other parts of the country. During the Civil Rights Movement of the 1960s, these celebrations were eclipsed by the struggle for postwar civil rights, but grew in popularity again in the 1970s with a focus on African-American freedom and African-American arts. As of 2021, South Dakota is the only state that does not recognize Juneteenth, according to the Congressional Research Service; North Dakota approved recognition of Juneteenth on April 13, 2021, with Hawaii becoming the 49th state to recognize the holiday on June 16, 2021. Modern observance is primarily in local celebrations. Traditions include public readings of the Emancipation Proclamation, singing traditional songs such as “Swing Low, Sweet Chariot” and “Lift Every Voice and Sing“, and reading of works by noted African-American writers, such as Ralph Ellison and Maya Angelou. Celebrations include rodeos, street fairscookoutsfamily reunions, park parties, historical reenactments, and Miss Juneteenth contests. Juneteenth is also celebrated by the Mascogos, descendants of Black Seminoles who escaped from US slavery in 1852 and settled in CoahuilaMexico. Juneteenth is the first new federal holiday since Martin Luther King Jr. Day was declared a holiday in 1986.
