Really saddened to hear the American soprano Roberta Alexander died yesterday at the age of 76. A wonderful Jenufa at Glyndebourne, and Handel's Theodora on disc with Harnoncourt. Here singing Samuel Barber's Sure on This Shining Night. A lovely, lovely artist. RIP

Flink meer Amerikaanse studenten meldden zich dit studiejaar bij de UvA. De politieke situatie in Amerika maakt het land minder aantrekkelijk voor studenten. ‘Ook het collegegeld is hier lager.’ www.folia.nl/nl/actueel/1...

Significantly more American students applied at the University of Amsterdam (UvA) this academic year. The political situation in America is making the country less attractive to students. “Tuition fees are also cheaper here.” www.folia.nl/en/actueel/1...

There is an important conversation that should be going on (maybe at the UN level?) about this, as it will become worse with time (as more satellites are orbited).

Nations worked together to build the Montreal Protocol to protect the Ozone Layer.

These constellations threaten all of that work.

BREAKING: Our client Mario Guevara, an Emmy-winning journalist detained by ICE in retaliation for livestreaming law enforcement activity, will be deported tomorrow to El Salvador.

Mario and his family are being punished for his reporting. This cruelty is meant to stifle our free press.

These towers surround Gaza's Roman Cemetery — an ancient intact burial site with 125 tombs that was discovered in 2022. @premiereurgenceint.bsky.social worked on the site before the war: www.theartnewspaper.com/2023/07/26/r...

Pritzker: "One of the reasons Trump wants to send troops into cities is bc he wants to be able to take control of the 2026 elections...if they've got troops in cities, & it becomes a kind of norm for people, then it won't be abnormal for them when they're going to vote having troops at ballot boxes"

De reactie van gematigd rechts op rechtsextremisme bepaalt hoe het de democratie vergaat
In de VS wordt de cancelcultuur van Donald Trump geholpen door bedrijven. In Nederland is het de VVD die extreemrechts normaliseert.

The main panel of this graphic is Chandra data that has been selected to show the location of different elements in the remains of the explosion: silicon (red), sulfur (yellow), calcium (green) and iron (purple). The blue color reveals the highest-energy X-ray emission detected by Chandra in Cas A, with the blue outer ring highlighting the expanding blast wave from the original explosion hundreds of years ago. The inset to the upper left zooms in a smaller region of Cas A. This reveals data collected by Chandra that picks up relative amounts of silicon and neon.

About 26 years ago, the Chandra X-ray Observatory released its "First Light" images. The supernova remnant Cassiopeia A was the highlight. All of these years later, Chandra is still delivering discoveries about this exploded star.

A truly outrageous and sickening request from the Netanyahu government.

The U.S. should not be complicit in or use ANY governmental, American taxpayer resources to aid and abet what amounts to the ethnic cleansing of Palestinian civilians from Gaza. 

We cannot stand for this.

The US Senate is not willing to go along with Trump’s proposed cancellation of dozens of NASA missions. 🧪🔭 #planetsci
voosen.me Paul Voosen @voosen.me · Jul 18
On NASA, it pretty much goes mission-by-mission, pushing back on all the proposed cancellations throughout all of SMD. The lead text is worth reading.
The Committee provides $7,300,000,000 for Science, which is $34,200,000 below the fiscal year 2025 enacted level. The Science account encompasses: Earth Science, Planetary Science, Astrophysics, Heliophysics, and Biological and Physical Science. This funding supports NASA programs that seek to answer fundamental questions concerning the ways in which Earth is changing; the comparison of Earth with other planets in the solar system and around other stars; the connections between the Sun and Earth; and the origin and evolution of planetary systems, the galaxy, and the universe, including the origin and distribution of life in the universe. These objectives are assisted by input from the scientific community through decadal surveys and are achieved through orbital and suborbital experiments, robotic flight missions, ground- based scientific research and data analysis, and the development of new technologies for future missions. NASA shall continue its progress toward implementing the recommendations of decadal surveys in Earth Science, Heliophysics, Planetary Science, Astrophysics, and Biological and Physical Sciences. The Committee rejects the mission terminations proposed in the fiscal year 2026 budget request for Earth Science, Planetary Science, Astrophysics, and Heliophysics. The Committee is concerned by the plan to end 55 missions across Science, which was driven by budget pressure rather than scientific value. The operating missions that are providing valuable scientific data should undergo the Senior Review process. Meanwhile, missions that are at the end of development and have been confirmed should proceed to launch at the earliest possible date. The Committee is open to collaborating with NASA to implement Senior Review findings. ...
