I recall how we have George Washington's bar bills.

And also how Washington regularly took laudanum for chronic pain management.

Lost Pulsars

In a recent SETI Live conversation, @planetarypan.bsky.social spoke with William J. Welch Postdoctoral Fellow Dr. Karen Perez, lead author of a new study reporting the possible discovery of a pulsar candidate near the Galactic Center. πŸ§ͺ πŸ”­ πŸ‘©β€πŸ”¬

US House rejects war powers resolution to end Trump’s hostilities with Iran Democratic-backed measure that would have forced US to withdraw troops failed by a vote of 212-219

219 Representatives refused to do their jobs and stop Donald Trump's illegal war.

While they did, Trump threatened to start another.

Yet again, USA:

Require that Congress end all of this, #ImpeachTrump, and remove him.

Give them no choice otherwise.

This is the second of six galaxies from Proposal 10550 I plan to process. They are all low surface brightness galaxies. I don't know much about them and that's why they interest me. There are very few Milky Way stars in this picture and many background galaxies for comparison to the foreground one. I tried to include as many as possible. Because these are remarkable for their lack of brightness, I have decided that it would be best to not try to brighten them a lot with processing, especially not relative to the other objects in the field.

It is not very noticeable but the chip gap is running vertically down the left side of the galaxy. It should be easy to see the faked filler zoomed 100%. It's just a thin line that would otherwise be blank that I've matched the brightness of the galaxy to and added some noise on top of. I used to think I shouldn't do this but if I always note that I did so then I think it is permissible. There are so many pictures in the archive that almost nobody will ever see otherwise.

Pete Hegseth is a Christian. So is JD Vance. So is Donald Trump.

Christians who advocate horrific crimes and mass death are still Christians.

To pretend otherwise is to give a pretext for avoiding addressing the systemic problem.

Estimates for what would have happened had YR4 impacted the Moon were for a roughly 1 km crater and an impact flash peaking around apparent magnitude -3.

To the eye, it would have been a dot that would have not been immediately obvious (since nearly all of the risk corridor was on the day side).

A lot of people seem to have really wanted 2024 YR4 to impact the Moon.

There will be other impactors.

The House is voting on a War Powers Resolution to end Trump's illegal war in Iran.

The price of unchecked war powers is paid by innocent civilians and servicemembers sent into harm’s way.

Voting YES to put a check on Trump's reckless abuse of power.

Goodbye and good riddance.

But don’t take the bait. Firing Noem alone won’t halt Trump’s campaign of terror.

The atrocities happening by ICE behind the walls of detention facilities and in broad daylight have proven that ICE cannot be reformed.

Abolish ICE NOW.

The sky brightness depends considerably on where in Minneapolis and Saint Paul one is standing.

And do not let Mullin, who defames people murdered by ICE, be appointed to anything.

I have had scammers spoof numbers belonging to medical centers here in Minnesota, which I cannot set my phone to filter out.

That has variously included their impersonating cardiology, oncology, and the emergency room.

St. Paul City Council weighs extending eviction notice to 60 days The new requirement would take effect May 14.

A significant number of kids here in Saint Paul will be on temporary virtual education for another week because of ICE and the Border Patrol.

And the city council is extending eviction protections for the rest of the year.

None of this is over.
