Maybe an uncommon opinion, but as someone who’s invested hundreds of hours into both games, I actually prefer the 2d experience of ROR quite a lot more than the 3d of ROR2.
A new investigation with NASA’s James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb’s discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the...
Scientists have been working on models of planet formation since before we knew exoplanets existed. Originally guided by the properties of the planets in our Solar System, these models turned out to be remarkably good at also accounting for exoplanets without an equivalent in our Solar System, like super Earths and hot Neptunes....
Astronomers have uncovered a link between Neptune’s shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun’s entangled magnetic fields drives solar activity.
Giant black holes were supposed to be bit players in the early cosmic story. But recent James Webb Space Telescope observations are finding an unexpected abundance of the beasts.
Magnetars are some of the most extreme objects we know about, with magnetic fields so strong that chemistry becomes impossible in their vicinity. They’re neutron stars with a superfluid interior that includes charged particles, so it’s easy to understand how a magnetic dynamo is maintained to support that magnetic field. But...
New observations of a faraway rocky world that might have its own magnetic field could help astronomers understand the seemingly haphazard magnetic fields swaddling our solar system’s planets.

Hopefully this means more games like Soma, which had much more of an emotional core than the rest of their catalog. (I know, I know, Soma was also a horror game, but the horror elements were arguably the least interesting part.)
While rovers have made incredible discoveries, their wheels can hold them back, and erratic terrain can mean damage. There is no replacing something like Perseverance, but sometimes rovers could use a leg up, and they could get that from a small swarm of four-legged robots.
Does anyone have an idea if this is anywhere near the mass needed to account for “dark matter”?
It’s not, unfortunately. In the context of dark matter, objects like this are referred to as “MACHOs” (or Massive Compact Halo Objects). These have been considered as a possible solution to the dark matter problem for decades, but sky surveys have failed to find them in sufficient numbers to account for even a fraction of the missing mass.
Another important consideration is where these object are in the galaxy. We know that dark matter mostly exists in an extended shell (usually referred to as a halo — hence the H in MACHO) that surrounds the galaxy, rather than being embedded inside it. Rogue planets are expected to be intermixed with the rest of the “light matter” in the galaxy, rather than distributed in this extended halo region.
Very cool find if this is confirmed! Trojan planets have long been predicted by simulations, but never actually observed in practice. If this is real, it could do a lot to help refine our models of planetary formation.
On Wednesday, researchers announced the discovery of a new astronomical enigma. The new object, GPM J1839–10, behaves a bit like a pulsar, sending out regular bursts of radio energy. But the physics that drives pulsars means that they’d stop emitting if they slowed down too much, and almost every pulsar we know of blinks at...
[…]to accurately interpret some of the neutron stars’ signals, researchers must first understand what goes on inside them. They have their hunches, but experimenting directly on a neutron star is out of the question. So scientists need another way to test their theories.

Researchers have discovered the most distant active supermassive black hole to date with the James Webb Space Telescope. The galaxy, CEERS 1019, existed just over 570 million years after the big bang, and its black hole is less massive than any other yet identified in the early universe. Not only that, they’ve easily “shaken...

Researchers using NASA’s James Webb Space Telescope have made major strides in confirming the source of dust in early galaxies. Observations of two Type II supernovae, Supernova 2004et (SN 2004et) and Supernova 2017eaw (SN 2017eaw), have revealed large amounts of dust within the ejecta of each of these objects.

The spacecraft emerged from the...

Exactly. Don’t get me wrong, I’m a huge privacy advocate… But the expectation of privacy that they have is completely unreasonable. “Nothing ever gets deleted from the internet” is an adage for a reason. If you’re concerned about people on this internet seeing something, don’t post it! Having the expectation that you’ll be able to “take back” anything you post is naive and unreasonable.
On June 25, 2023, NASA’s James Webb Space Telescope turned to famed ringed world Saturn for its first near-infrared observations of the planet. The initial imagery from Webb’s NIRCam (Near-Infrared Camera) is already fascinating researchers.
The hypothetical “planet 9” that astronomers have been actively searching for during the past several years is expected to orbit somewhere between the Kuiper belt and the Oort cloud — and we absolutely do have the technology to detect it, it’s just painstaking work that takes a lot of telescope time (which is in short supply since lots of astronomers are all competing for it) and is difficult to automate.
