Nothing can escape a black hole. General relativity is very clear on this point. Cross a black hole’s event horizon, and you are forever lost to the universe. Except that’s not entirely true. It’s true according to Einstein’s theory, but general relativity is a classical model. It doesn’t take into account the quantum aspects of nature. For that, you’d need a quantum theory of gravity, which we don’t have. But we do have some ideas about some of the effects of quantum gravity, and one of the most interesting is Hawking radiation.

Nothing says springtime on Mars like defrosting dunes.

As Russia wages its terrible war against its neighbour Ukraine, the deteriorating situation inside Russia is leading many Russians to flee the collapsing economy. According to Russian journalist Kamil Galeev, Roscosmos Director Dmitry Rogozin is prohibiting Roscosmos employees from leaving the increasingly isolated nation.

If humanity is ever going to find life on another planet in the solar system, it’s probably best to know where to look.  Plenty of scientists have spent many, many hours pondering precisely that question, and plenty have come up with justifications for backing a particular place in the solar system as the most likely to hold the potential for harboring life as we know it.  Thanks to a team led by Dimitra Atri of NYU Abu Dhabi, we now have a methodology by which to rank them.

The next step to understanding exoplanets is to understand their atmospheres better. Astronomers can determine a planet’s mass, density, and other physical characteristics fairly routinely. But characterizing their atmospheres is more complicated.

One way to inspire kids to get interested in STEM is to introduce them to it at an early age.  Lego is one of the best gateways to that interest, and the company has been busy churning out space-themed toys for most of its existence.  Now another entry has joined that long, distinguished line of interlocking brick system designs – the Rocket Launch Center, #60351.

Last week, a small asteroid was detected just two hours before it impacted Earth’s atmosphere. Luckily, it was only about 3 meters (10 feet) wide, and the space rock, now known as 2022 EB5 likely burned up in Earth’s atmosphere near Iceland at 21:22 UTC on March 11.

Russia’s invasion of Ukraine has led to an outpouring of support and material aid from the international community. For his part, Elon Musk obliged Ukrainian Vice Prime Minister Mykhailo Fedorov‘s request for assistance by sending free Starlink terminals to Ukraine. For some besieged communities, like the city of Mariupol, this service constitutes the only means of getting up-to-date information, communicating with family members, or sharing their stories from the front lines of the war.

Astronomers have watched the young binary star system SVS 13 for decades. Astronomers don’t know much about how planets form around proto-binary stars like SVS 13, and the earliest stages are especially mysterious. A new study based on three decades of research reveals three potentially planet-forming disks around the binary star.

If dark matter is out there, and it certainly seems to be, then what could it possibly be? That is perhaps the biggest mystery of dark matter. The only known particles that match the requirement of having mass and not interacting strongly with light are neutrinos. But neutrinos have low mass and zip through the cosmos at nearly the speed of light. They are a form of “hot” dark matter, so they don’t match the observed data that require dark matter to be “cold.” With neutrinos ruled out, cosmologists look toward various hypothetical particles we haven’t discovered, and perhaps the most popular of these are known as axions.

Sometimes in space, even when you’re millions of kilometers from anything, you’re still being watched.  Or at least that’s the case for the Parker Solar Probe, which completed the 11th perihelion of its 24 perihelion journey on February 25th.  While the probe was speeding past the Sun, it was being watched by over 40 space and ground-based telescopes.

This will likely come as a surprise to no one who has closely watched the development of NASA’s next giant rocket, the Space Launch System (SLS), but it’s going to be expensive to use.  Like, really expensive – to the tune of $4.1 billion per launch, according to the NASA Inspector General.  That’s over double the original expected launch cost.

For millennia, humans have gazed at the northern lights with wonder, pondering their nature and source. Even today, these once mysterious phenomena still evoke awe, though we understand them a little better now. Still, most of our knowledge about the northern lights has come recently, in the last century or two. Astronomers and meteorologists of the 1800s worked for years to understand the aurora, wondering if they were a feature of Earth’s atmospheric weather, of outer space, or, perhaps, something that straddled the boundary in-between. This centuries-old attempt to understand the northern lights was an immense, international-scale project, and, through fortunate happenstance, it even helped inspire one of the underlying foundations of modern society – time zones.

Using ground-based and space-based observations, a team of researchers has been monitoring a difficult-to-see comet carefully. It’s called Comet 323P/SOHO, and it was discovered over 20 years ago in 1999. But it’s difficult to observe due to its proximity to the Sun.

Since 1988, the Intergovernmental Panel on Climate Change (IPCC) was formed and tasked with advancing knowledge of humanity’s impact on the natural environment. Beginning in 1990, they have issued multiple reports on the natural, political, and economic impacts Climate Change will have, as well as possible options for mitigation and adaptation. On Feb. 27th, the IPCC released the second part of its Sixth Assessment Report (AR6) – “Impacts, Adaptation, and Vulnerability” – and the outlook isn’t good!

NASA’s Apollo missions to the Moon brought back about 382 kilograms (842 pounds) of samples, including rocks, rock cores, rock, pebbles, sand, and dust. Scientists have studied those samples intently over the decades and have learned a lot. But they haven’t studied all of the samples.

Dark energy is central to our modern theory of cosmology. We know the universe is expanding at an ever-increasing rate, and the clearest explanation is that some kind of energy is driving it. Since this energy doesn’t emit light, we call it dark energy. But simply giving dark energy a name doesn’t mean we fully understand it. We can see what dark energy does, but its fundamental nature is perhaps the biggest scientific mystery we have.
