WASHINGTON — A top Democrat said the House will vote Thursday on removing Rep. Marjorie Taylor Greene from her committees, intensifying the stakes over the Georgia Republican’s online embrace of conspiracy theories and violent racist views. The announcement by No. 2 House Democrat Steny Hoyer of Maryland came Wednesday as showdowns approached over Greene and Rep. Liz Cheney, who’ve antagonized opposing wings of a Republican Party struggling to define itself without Donald Trump in the White House. House Republicans, under bipartisan pressure to punish Greene, have been hoping to take action on their own — such as removing her from one committee — and avoid a difficult political vote for many in the GOP. But Hoyer released a statement saying that after speaking to House Minority Leader Kevin McCarthy, R-Calif., “it is clear there is no alternative to holding a floor vote on the resolution to remove Rep. Greene from her committee assignments. ” A McCarthy aide said he would discuss the situation with his GOP colleagues. McCarthy met for 90 minutes late Tuesday with Greene, R-Ga., and aides said little about the outcome. The hard-right freshman has burst onto the national political scene after using social media to endorse outlandish conspiracy theories and violent, racist views. Republicans had appointed Greene to the education committee, a decision that drew especially harsh criticism because of her suggestions that school shootings in Newtown, Connecticut, and Parkland, Florida, could be hoaxes. The Democratic-run House Rules Committee was meeting Wednesday in an initial step toward removing Greene from her committees, a rare step for Congress. A full House vote would be a political ordeal for many Republicans, forcing them to go on record defending or punishing a social media-savvy lawmaker who has won enthusiastic support from Trump. Greene was showing little sign of backing down. “No matter what @GOPLeader does it would never be enough for the hate America Democrats,” she tweeted early Wednesday. Meanwhile, House Republicans planned a closed-door meeting later Wednesday in which Cheney’s political fate could be decided. The GOP’s farthest right wing was itching to oust Cheney, of Wyoming, from her post as the No. 3 House Republican after she voted last month to impeach Trump. Cheney is a leader of her party’s traditional conservatives and is a daughter of former Vice-President Dick Cheney. The strife underscores Republican fissures as the party seeks a path forward two weeks after Trump left office as the only twice-impeached president. House Republicans are effectively deciding whether to prioritize the former president’s norm-shattering behaviour and conspiracy theories and retain the loyalty of his voters over more establishment conservative values. “We can either become a fringe party that never wins elections or rebuild the big tent party of Reagan,” Maryland Gov. Larry Hogan, one of the few elected Republicans who routinely rebuked Trump, said in a written statement. Without mentioning Cheney or Greene, he added, “I urge congressional Republicans to make the right choice.” But pro-Trump forces remain powerful. “We’ve got millions and millions of woke, motivated, America-first Trump voters that believe in the movement,” said John Fredericks, who led Trump’s Virginia campaigns in 2016 and 2020. “If you’re going to keep Liz Cheney in leadership, there’s no party.” The handling of Greene and Cheney presented a tricky balancing act for McCarthy. The eight-term lawmaker is hoping to become speaker should Republicans capture the House majority in the 2022 elections and has little interest in antagonizing any GOP colleagues. Penalizing Cheney for what she called her “vote of conscience” on impeachment would be awkward without also punishing Greene. Action against either risked angering the GOP’s numerous Trump supporters or its more traditional conservative backers. “You can’t do the normal political song and dance and appease this side slightly and appease that side slightly,” said former Rep. Mark Sanford, R-S.C., who lost a 2018 party primary after clashing with Trump. “The whole nature of the Trump phenomenon is there is no appeasement.” Senate Minority Leader Mitch McConnell, R-Ky., was building pressure on McCarthy. McConnell issued one statement praising Cheney as “a leader with deep convictions and courage.” In another statement that didn’t use Greene’s name, the usually circumspect McConnell called her “loony lies” a “cancer” on the GOP. His remarks were the latest indication of his concerns about letting the GOP’s most pro-Trump, hardest-right factions gain too much sway in the party. Sen. Mitt Romney, R-Utah, a Trump critic and the GOP 2012 presidential nominee, said Republicans must “separate ourselves from the people that are the wacky weeds.” On social media, Greene has voiced support for racist views, unfounded QAnon pro-Trump conspiracy theories and calls for violence against Democratic politicians, including House Speaker Nancy Pelosi. Greene herself tweeted fundraising appeals Tuesday that said, “With your support, the Democrat mob can’t cancel me,” beneath a picture of herself standing with Trump. McCarthy has stopped short of aggressively criticizing Greene, who was dubbed a “future Republican Star” by Trump last summer and has remained a firm Trump supporter. McCarthy has long been close to Trump. But he’s been criticized by some Republicans, mostly quietly, for relentlessly supporting Trump’s fallacious claims of a fraudulent election in November and for not forcefully criticizing Trump for helping provoke the deadly Jan. 6 attack on the Capitol by his supporters. Cheney foes have said they have enough votes to force her Cheney’s removal from her leadership job. But it was unclear Wednesday whether that vote among GOP lawmakers would occur or if McCarthy would somehow delay that showdown. McCarthy has said he supports Cheney but also has “concerns,” leaving his stance on her unclear. Rep. Matt Rosendale, R-Mont., a leader of the effort to oust Cheney, says he has enough support to succeed. “She’s brought this on herself,” Rosendale said.

Blood moon, big city: Skywatcher captures total lunar eclipse over New York – Galaxy Reporters
The moon during eclipse burns red high above the yellow lights of New York City in beautiful photos caught by novice astronomer Alexander Krivenyshev.
Alexander Krivenyshev is the president of WorldTimeZone.com, who snapped images of the total lunar eclipse on Sunday night (May 15) from Guttenberg, New Jersey, outside the Hudson River from the Big Apple.
Krivenyshev told Space.com through the email that he maintained through cloudy conditions to get shots of the blood-red moon glowing like a beacon in a light-polluted sky.
The eclipse started at 9:32 p.m EDT on Sunday (0132 GMT on May 16) when the moon nosed into the dark part of Earth’s shadow, recognized as the penumbra, and stopped five hours later. The total eclipse phase, in which Earth’s huger umbral shadow blackened the moon, survived 85 minutes longer than any lunar eclipse in 33 years.
Earth’s closest neighbor temporarily turns coppery red during entire lunar eclipses. This “blood moon” impact is caused by Earth’s atmosphere, which bends some red light throughout the lunar surface while scattering away shorter-wavelength light.

Last weekend’s sky show was nicely observed from America and fractions of Western Europe and West Africa. It was the first total lunar eclipse of the year; however, it won’t be the last. One more eclipse will occur on Nov. 8. The Nov. 8 lunar eclipse will be observed from Australia, eastern Asia, and the western United States.
Searching for the Milky Way's Black Hole – Skywatching – Castanet.net
When we look into the southern sky close to the horizon on summer evenings, we are looking towards the centre of our galaxy, the Milky Way.
It is lurking around 30,000 light years behind the stars making up the constellation of Sagittarius, “The Archer”. However, thanks to our location in the disc of our galaxy, our view is blocked by huge clouds of stars, gas and dust.
Our first images of the centre of the Milky Way were obtained by means of radio telescopes, which show us what the universe would look like if we could see radio waves rather than light. They revealed a strange, bright and unusually small radio source.
Measurements of the speeds stars orbit the centre of our galaxy indicate that at the same position as the bright radio source lies something very massive, very small and active. The best candidate to explain this is a black hole.
Radio waves have power to penetrate clouds and dust, which is why radar is so useful for navigation, detecting threats and avoiding hazards at night or in bad weather. However, radio waves have this greater penetration power because they are much longer than light waves. This means that to see detail when observing at radio wavelengths we need to use huge antennas.
To have the same ability to discern detail as the human eye, a radio telescope tuned to the wavelength of emissions from cosmic hydrogen (21cm) the antenna would need to be about a kilometre in diameter. Moreover, black holes are small by cosmic standards and at great distances, so to discern any details the radio telescope would need an antenna the size of the Earth.
This sounds impossible, but there is a solution, a technique called “Very Long Baseline Interferometry”.
In the 1960s, Canada was the first country to succeed in combining radio telescopes thousands of kilometres apart so that they would have the detail discerning ability of a radio telescope thousands of kilometres in diameter.
This procedure has made possible a powerful, new astronomical instrument, the Event Horizon Telescope (EHT).
Several radio telescopes, thousands of kilometres apart operate in collaboration to observe the centre of the Milky Way at the same time. One of them is the Atacama Large Millimetre Array, located in Chile, in which Canada is a partner. In addition, scientists at several Canadian universities are involved.
The collaboration is named after the boundary that forms around black holes, called the event horizon. This is a one-way boundary in space-time—stuff can fall in but nothing, not even light, gets out. This is why they are called black holes.
However, even if we cannot see the black holes directly, we can certainly see the disc of material swirling around the black holes as it gets sucked in. This stuff gets very hot, and has intense magnetic fields trapped in it, so the black hole announces itself with radio emissions and X-rays from that disc.
The first target for the Event Horizon Telescope was the galaxy M87, located some 55 million light years away. It had long been suspected that a very energetic black hole lies at its centre, a big one, around 5 billion times the mass of the Sun. The EHT gave us our first image of that black hole.
Then the EHT radio telescopes were turned on the centre of our galaxy, and got our first image of our black hole. Luckily for us, it is much less massive and active than the one at the centre of M87. At four million times the mass of the Sun, it is relatively tiny.
We believe most spiral galaxies have big black holes in their cores. It is not clear whether galaxies get them when they form or they appear later. However, learning about their roles in galaxies should tell us more about how galaxies form and evolve to the point where they develop stars and planets, and because we live in one, it would be nice to know.
• Venus, Jupiter, Mars and Saturn are still lined up in the dawn glow, in order of decreasing brightness.
• The Moon will be new on May 30.

Boeing's Starliner approaching ISS in high-stakes test mission – Phys.org
Boeing’s Starliner capsule was preparing to dock with the International Space Station Friday, in a high-stakes uncrewed test flight key to reviving the US aerospace giant’s reputation after a series of failures.
The spaceship blasted off from the Kennedy Space Center in Florida on Thursday evening, and is now set to rendezvous with the ISS at 7:10 pm Eastern Time (2310 GMT), as part of a mission to prove it is capable of providing safe rides for NASA astronauts.
Starliner encountered some propulsion problems early in its journey, with two thrusters responsible for placing it in a stable orbit failing for unclear reasons—though officials insisted everything remained on track.
“Overall, the spacecraft is doing really well,” Steve Sitch, program manager for NASA’s Commercial Crew Program told reporters at a post-launch press conference, in which he nonetheless flagged anomalies that engineers are working to understand.
One of 12 orbital maneuvering and attitude control (OMAC) thrusters located on Starliner’s aft side failed after one second, at which point a second thruster kicked in and took over, but also cut out after 25 seconds.
The ship’s software then engaged a third thruster that completed the necessary burn.
The OMAC thrusters are set to be used to bring Starliner closer to the ISS, and to help de-orbit the spacecraft near the end of the mission.
“We’ll go look at the data and try to understand what happened. And then from a redundancy perspective, can we recover those thrusters?” said Sitch.
Starliner’s success is key to repairing Boeing’s frayed reputation after its first launch, back in 2019, failed to dock with the ISS due to software bugs—one that led to it burning too much fuel to reach its destination, and another that could have destroyed the vehicle during re-entry.
A second try was scheduled in August 2021, but the capsule was rolled back from the launchpad to address sticky valves that weren’t opening as they should, and the vessel was eventually sent back to the factory for fixes.
NASA is looking to certify Starliner as a second “taxi” service for its astronauts to the space station—a role that Elon Musk’s SpaceX has provided since succeeding in a test mission for its Dragon capsule in 2020.
Both companies were awarded fixed-price contracts—$4.2 billion to Boeing, and $2.6 billion to SpaceX—in 2014, shortly after the end of the Space Shuttle program, during a time when the United States was left reliant on Russian Soyuz rockets for rides to the orbital outpost.
Boeing, with its hundred-year history, was considered by many as the sure shot, while then-upstart SpaceX was less proven.
In reality, it was SpaceX that rocketed ahead, and recently sent its fourth routine crew to the research platform—while Boeing’s development delays have cost the company hundreds of millions of dollars.
Starliner should dock with the ISS about 24 hours after launch, and deliver more than 800 pounds of cargo.
Its sole passenger is a mannequin named Rosie the Rocketeer—a play on the World War II campaign icon Rosie the Riveter—whose job is to collect flight data with her sensors in order to learn what human astronauts would experience.
“We are a little jealous of Rosie,” NASA astronaut Mike Fincke, who is expected to be among the first crew selected for a manned demonstration mission should OFT-2 succeed, said at a press conference this week.
The gumdrop-shaped capsule will spend about five days in space, then undock and return to Earth on May 25, using giant parachutes to land in the desert of the western United States.
NASA sees a second provider to low Earth orbit as a vital backup, should SpaceX encounter problems.
