one of my third graders has a special talent for making 2-frame comics that really speak to me
Hold your nose at this science pun.
“Normally lasting weeks or months, a new record has just been set for TDEs. XJ1500+0154, 1.8 billion light years away, is the largest, longest-lasting one ever seen. First detected in July of 2005, the X-rays from this distant source brightened by a factor of 100 over 3 years. They remain bright even today. Although dozens of TDEs have been observed since the 1990s, none have lasted this long. It may be caused by the most massive star ever observed creating a TDE.”
When any object passes too close to the event horizon of a black hole, the tidal forces acting on it can become so strong that they’ll tear the entire object apart in a spaghettification disaster. While most of the matter will get ejected from the encounter, a significant fraction can be accreted, absorbed and used to fuel the black hole’s growth. These tidal disruption events have been seen numerous times since the launch of our X-ray observatories, and are now known to come in a wide variety of magnitudes, at a variety of distances and to last a variable amount of time. So when you see the largest, longest-lasting one ever, you sit up and take notice! That’s exactly what’s happened with XJ1500+154, which is now in its second decade of X-ray signals.
Come get the full story on this amazing object, and learn how it might solve the puzzle of supermassive black hole growth on today’s Mostly Mute Monday!
The cloud chamber, also known as the Wilson chamber, is a particle detector used for detecting ionizing radiation.
In its most basic form, a cloud chamber is a sealed environment containing a supersaturated vapor of water or alcohol. When a charged particle (for example, an alpha or beta particle) interacts with the mixture, the fluid is ionized. The resulting ions act as condensation nuclei, around which a mist will form (because the mixture is on the point of condensation).
The high energies of alpha and beta particles mean that a trail is left, due to many ions being produced along the path of the charged particle. These tracks have distinctive shapes, for example, an alpha particle’s track is broad and shows more evidence of deflection by collisions, while an electron’s is thinner and straight. -(x)

Time for another comic on our reddish dwarf planet, Makemake!
(Polaris is pushed for tomorrow ;) )

The official page of Drunk Science! An enthusiastic host performs simple experiments and then humorously explains the science behind the result, all while visibly drunk.
