China launches communications test satellite

9:19 am

China today successfully launched a communications satellite designed according to its state-run press to test new communication technologies, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages and four strap-on boosters, all using toxic hypergolic fuels, crashed inside China.

The leaders in the 2024 launch race:

124 SpaceX
57 China
15 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 143 to 85, while SpaceX by itself leads the entire world, including American companies, 124 to 104.

The Democratic Party for the past half century
The Democratic Party for the past half century

While the conservative press is today going ga-ga over Joe Biden’s pardoning of his son Hunter yesterday — noting accurately that Biden’s action proved himself once again to be a liar and a fraud, having spent the last four years insisting he would never do such a thing while also insisting that “no one is above the law” — I think it more instructive to look at what some of the most rabid partisan leftists have been saying, before and after the election of Donald Trump.

You see, some of these partisan leftists are actually doing something I have not seen a partisan leftist do since before Bill Clinton was president — they are showing an ability to have an open mind.

Let’s begin with two members of a leftist podcast group dubbed the Young Turks that for years saw nothing good about any Republican and considering Donald Trump the epitomization of the devil himself. Anything Trump did was wrong. Everything Trump and the Republicans represented was evil and must be opposed blindly. During and after this presidential election campaign however two of the more noted members of this podcast, Ann Kasparian and Cenk Uygar, changed their tune, and did so in an astonishing way.

First there was Kasparian’s announcement in October that she has left the Democratic Party. Watch:

New stars shaped by old stars

New stars shaped by old stars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a study focused on looking at star formation in nearby galaxies. From the caption:

Evidence of star formation is scattered all around NGC 1637, if you know where to look. The galaxy’s spiral arms are dotted with what appear to be pink clouds, many of which are accompanied by bright blue stars. The pinkish colour comes from hydrogen atoms that have been excited by ultraviolet light from young, massive stars. This contrasts with the warm yellow glow of the galaxy’s centre, which is home to a densely packed collection of older, redder stars.

The stars that set their birthplaces aglow are comparatively short-lived, and many of these stars will explode as supernovae just a few million years after they’re born. In 1999, NGC 1637 played host to a supernova, pithily named SN 1999EM, that was lauded as the brightest supernova seen that year. When a massive star expires as a supernova, the explosion outshines its entire home galaxy for a short time. While a supernova marks the end of a star’s life, it can also jump start the formation of new stars by compressing nearby clouds of gas, beginning the stellar lifecycle anew.

This galaxy is one worth keeping an eye on for supernovae, since every one of those blue stars has the potential of erupting.
