A rare tornado just went thru heavily populated Montgomery County, MD, northwest of Washington D.C. Now headed towards Baltimore.

Not sure if it touched down or caused heavy damage.

Trump making no bones about his vindictive slash and burn plans in a 2nd term.
"Wouldn't it be terrible to throw the president's wife and the former secretary of state into jail? Wouldn't that be a terrible thing? It's a terrible, terrible, path that they're leading us to. And it's very possible that it's going to have to happen to them."

Preparations for NASA’s Boeing Starliner Crew Flight Test Launch are in progress.

Launch time: 12:25 pm ET

"The two NASA astronauts aboard, flight commander Butch Wilmore and pilot Suni Williams, will test the end-to-end capabilities of the Starliner system, including launch, docking, and return to Earth. After a one-week stay docked to the International Space Station, the Starliner and crew will land under parachutes in the western United States."

Starliner launch is now scheduled for 10:52 a.m. EDT Wednesday, June 5.

"The ULA team identified an issue with a single ground power supply within one of the 3 redundant chassis that provides power to a subset of computer cards controlling various system functions, including the card responsible for the stable replenishment topping valves for the Centaur upper stage."
The faulty chassis have been replaced with a spare unit.

This week, a science team announced the discovery of JADES-GS-z14-0, a galaxy that existed just 290 million years after the big bang. JADES-GS-z14-0 now holds the record for the most distant known galaxy, with redshift z=14.32.

The discovery is based on spectroscopic measurements made using the Webb telescope of light from this distant galaxy that has traveled for over 13.5 billion years.

What's the metallicity? Could any of these have formed planets?

AkaSci, (edited )
@AkaSci@fosstodon.org avatar

@TMEubanks
From the paper - "We estimate a gas-phase metallicity of log (Z/Z⊙) = −1.5 (+0.7, −0.4)."
I.e., Z/Z⊙ = 0.032

Obviously, galaxy JADES-GS-z14-0 has a lower metallicity than the Sun.

Metallicity = the mass fraction of elements heavier than helium.

Fresh volcanic eruptions north of Grindavîk, Iceland.

  • Started at 1 pm local (UTC)
  • Fissure location is similar to Dec 19 and Mar 16 eruptions
  • Strong M4.1 earthquake in the area around 11 am
  • Magma likely in contact with groundwater causing explosions and dark plumes of smoke
  • Grindavík, the Blue Lagoon and the power plant in Svartsengi evacuated
  • This eruption is the most powerful in the current system so far.

29 May 1953 - Edmund Hillary, an explore and mountaineer from New Zealand, and Tenzing Norgay, the Nepalese Sherpa mountaineer, became the first people to stand on the summit of Mt. Everest, the world’s highest peak.

The pic of Tenzing below was taken by Edmund Hillary using the Kodak Retina 118 camera. The camera is displayed at the Otago Museum in Dunedin, New Zealand.

Interestingly, Edmund Hillary and Tenzing Norgay reached the summit of Mt. Everest on Tenzing Norgay's birthday.

Tenzing Norgay was born on May 29, 1914 in Tengboche, Khumbu, in northeastern Nepal.

From https://en.wikipedia.org/wiki/Tenzing_Norgay - "Although his exact date of birth is unknown, he knew it was in late May by the weather and the crops. After his ascent of Everest on 29 May 1953, he decided to celebrate his birthday on that day thereafter."

Happy Birthday to Frank Drake (May 28, 1930 – Sept 2, 2022), astrophysicist, astrobiologist and creator of the Drake equation, which is used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy.

The equation was formulated in 1961 as a way to stimulate discussion at the 1st scientific meeting on the search for extraterrestrial intelligence (SETI) at the National Radio Astronomy Observatory site at Green Bank, WV.

Frank Drake on the Drake Equation:
"It amazes me to this day to see it displayed prominently in most textbooks on astronomy, often in a big important-looking box.
...
I’m always surprised to see it viewed as one of the great icons of science, because it didn’t take any deep intellectual effort or insight on my part. But then, as now, it expressed a big idea in a form that a scientist, even a beginner, could assimilate."

The price is rising for buying the government and destroying Democracy under republican rule.

"
When Donald Trump met some of the country’s top donors at a luxurious New York hotel earlier this month, he told the group that a businessman had recently offered $1 million to his presidential effort and wanted to have lunch.

“I’m not having lunch,” Trump said he responded, according to donors who attended. “You’ve got to make it $25 million.”

Craig Caplan of CSPAN reports -

"Republican presidential candidate Donald J. Trump only received .65% (6 votes) as a write in candidate in the first round of voting to be the 2024 Libertarian Party presidential candidate."

6 votes! And a lot of Boos.
Let's plan to make it happen again in November.

Also, "Robert F. Kennedy Jr. was eliminated as the 2024 Libertarian Party presidential candidate in the first round of voting with 2.07% (19 votes) at their national convention in DC."

Press Trust of India and others are reporting a max. temperature of 52.3°C in Mungeshpur.

45+ degrees Celsius across much of central and northern India yesterday.

Temperatures in India, like the rest of the world, have been rising due to Climate Change.

India is ranked 4th among the list of countries most affected by climate change in 2015.

This is the 3rd straight year of severe heatwaves in India and the 6th in the last 10 years (see table below).

Temp. rises are also causing Himalayan glaciers to retreat, threatening the flow rate of major rivers.

The largest camera ever built for astrophysics arrived this week at the Rubin Observatory at Cerro Pachón in Chile.

The LSST camera, built by the SLAC National Accelerator Laboratory in Menlo Park, CA, is the final major component of the Rubin Observatory's Simonyi Survey Telescope to arrive at the summit.

Development of the observatory has been funded by the NSF and the DOE.

First light is expected in Dec 2024.

The Rubin Observatory Simonyi Survey Telescope consists of 3 aspheric mirrors: an 8.4-m primary mirror M1, a 3.5-m convex secondary mirror M2, and a 5.0-m tertiary mirror M3.

The primary and tertiary mirrors are fabricated from a single piece of glass.
The secondary mirror (M2) is the largest convex mirror ever made.
Field of view = 3.5°.
The 3.2-gigapixel camera hangs below the secondary mirror.

The focal plane of the Vera C. Rubin telescope consists of 189 charge-coupled device (CCD) sensors, arranged in a total of 21 3-by-3 square arrays. The system is cooled to about -100 °C to minimize noise.

The 3.5° field of view of the 64 cm wide array is 40 times the area of the full moon in the sky.

Camera Data Rates: ~3.2 GBytes/sec peak raw data
1 pixel = 16 bits (raw)
Pixels: 3.2 billion!
Detector read-out time: 2 sec
