I remember my father bringing one of these home, probably late 1984. It weighed something like 30 pounds and I couldn’t lift it off the floor. Even had a 5MB (?) hard disk installed.

He had to carry it on the train to and from the office, until it was eventually replaced with a IBM PC Convertible.

An infographic titled "How BIG are the BLACK HOLES we find with GRAVITATIONAL WAVES?" by @astronerdika. The graphic displays a range of black hole masses detected via gravitational waves, categorized by their size in solar masses (mass of the Sun) and represented with playful cat-like black hole illustrations.

The categories from left to right are:

1. "<5 times the mass of the Sun"
- Labeled "smol"
- Very small black hole illustration represented by a curled up black cat
- Arrow pointing left: "THIS WAY TO NEUTRON STARS"
- Example: "Big component of GW230529 (~3.6 times the mass of the Sun)"

2. "~10 times the mass of the Sun"
- Labeled "basic"
- Slightly larger black hole cat illustration
- Caption: "LOTS OF BLACK HOLES"

3. "~35–45 times the mass of the Sun"
- Labeled "hefty"
- Bigger black hole cat illustration
- Continues the idea of a populated range

4. ">60 times the mass of the Sun"
- Labeled "chonky"
- Large black hole cat illustration
- Caption: "FORBIDDEN TERRITORY? (can these even be made from the collapse of star cores?!)"
- Example: "Components of GW190521 (~85 + ~66 times the mass of the Sun)"

5. ">100 times the mass of the Sun"
- Labeled "oh lawd"
- Very large, curled-up black hole cat illustration
- Arrow pointing right: "THIS WAY TO INTERMEDIATE MASS BLACK HOLES"
- Example: "Components of GW231123 (~137 + ~103 times the mass of the Sun)"

Below the categories is a stylized black curve representing the inferred population of black holes detected by LIGO-Virgo-KAGRA. It rises sharply in the "basic" range and falls off toward the "hefty" and "chonky" ranges, with a note reading:
"this curve is an artistic representation of the black hole population inferred by LIGO-Virgo-KAGRA."

This infographic draws from the β€œChonky Cat” meme.

Heard the latest news from the LIGO-Virgo-KAGRA collaboration? We detected the collision of the most massive pair of black holes so far: #GW231123 weighing in at ~137 + ~103 times the mass of the Sun!

So to celebrate, here’s a handy chart ✨

Just how chonky are these black holes? πŸ€”

Dive into this spectacular image of the stellar nursery IC 2944!

You see those thick clouds of dust? They are being bombarded by the UV radiation from nearby stars, and are likely to be destroyed before they can collapse and form new stars.

This cluster of stars is known as Messier 15, and is located some 35,000 light-years away in the constellation of Pegasus (The Winged Horse). It is one of the oldest globular clusters known, with an age of around 12 billion years. This new image is made up of observations from Hubble's Wide Field Camera 3 and Advanced Camera for Surveys in the ultraviolet, infrared, and optical parts of the spectrum. (NASA, ESA)

Figure 1. Comparing two theoretical isochrones we constructed with different ages, MC parameters, distance, and reddening. The observational data for M15 is plotted in the background, with photometric uncertainty estimated from the AS test plotted on the right.

This is the globular cluster M15, imaged by Hubble. It's a great target for binoculars or backyard telescopes, in the constellation Pegasus.

Jiaqi Ying et al. measured M15's age with 3% precision. This group of stars formed *immediately* after the Universe did.

What's the magical green glow that dominates the sky in this pic of ESO’s La Silla Observatory? 🧐

Known as airglow, it's a faint light emitted by the Earth’s atmosphere and it is only visible in the darkest of places.

What causes it? Find out here: www.eso.org/public/image...
