How the Big Bang got its name

  2 months ago (Wed, Mar 27, 2024 at 09:02 AM)

You might have heard this one before: astronomer Fred Hoyle coined the phrase ‘Big Bang’ to make fun of a theory of the Universe’s origins that he disliked. Wrong, writes historian Helge Kragh. Hoyle did originate the catchy term — in a 1949 popular-science talk for BBC radio — but it was never intended as ridicule. And most people, including Hoyle, pretty much ignored it for decades afterwards. In 1965, the discovery of the cosmic microwave background signalled the triumph of the theory, ‘Big Bang’ made it into a New York Times headline, and the term snowballed into the popular ...   Continue reading ››

Galaxy AM 1054-325 has been distorted into an S-shape from a normal pancake-like spiral shape by the gravitational pull of a neighboring galaxy, seen in this Hubble Space Telescope image. A consequence of this is that newborn clusters of stars form along a stretched-out tidal tail for thousands of light-years, resembling a string of pearls. A new study led by a Penn State astronomer homed in on 12 of these tidal tails and found 425 star clusters, each with as many as a million newborn stars.

Einstein’s Insight: Why Does Gravity Pull Us Down and Not Up?

  5 months ago (Thu, Dec 28, 2023 at 10:37 AM)

Why does gravity pull us down and not up?

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars.

Magnets attract some types of metals, but they can also push other magnets away. So how come you feel only the pull of gravity?

In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetim...   Continue reading ››

Researchers at ETH Zurich’s Marsquake Service have been studying data from the NASA InSight mission’s seismometer on one of our neighboring planets. For over three years, the only seismic waves identified on Mars were those that traveled through the planet’s depths from each quake’s focus or hypocenter. However, the scientists had always hoped for an event that would also cause waves to move throughout the planet’s surf...   Continue reading ››








New Research Indicates That Mars Was Capable of Supporting Life

  1 year ago (Wed, Nov 30, 2022 at 07:50 PM)

 SETI Institute
Early Mars might have been a warm version of modern Titan and at least as promising, if not more promising, as a location for the origin of life.

A new study reveals that Mars was born wet, with a dense atmosphere allowing warm-to-hot oceans for millions of years. This discovery was recently published in the journal Earth and Planetary Science Letters. To arrive at this conclusion, researchers created the first model of the evolution of the Martian atmosphere, which links the high temperatures associated with Mars’ molten formation to the creation of the first oceans and atmosphere.

Astronomers discover closest black hole to Earth

  2 years ago (Mon, Nov 07, 2022 at 01:37 PM)

 National Optical-Infrared Astronomy Research Laboratory
Black holes are the most extreme objects in the universe. Supermassive versions of these unimaginably dense objects likely reside at the centers of all large galaxies. Stellar-mass black holes—which weigh approximately five to 100 times the mass of the sun—are much more common, with an estimated 100 million in the Milky Way alone.

Only a handful have been confirmed to date, however, and nearly all of these are "active"—meaning they shine brightly in X-rays as they consume material from a nearby stellar companion, unlike dormant black holes which do not.

Until now, Mars has generally been considered a geologically dead planet. An international team of scientists now reports that seismic signals indicate vulcanism still plays an active role in shaping the Martian surface.

Ever since the NASA InSight Mission deployed the SEIS seismometer on the surface of Mars in 2018, seismologists and geophysicists at ETH Zurich have been listening to the seismic pings of more than 1,300 marsquakes. Again and again, the researchers registered smaller and larger Mars quakes. A detailed analysis of the quakes’ location and spectral character eventually brou...   Continue reading ››








How Did the Earth and Moon Form? The Surprising Role of Magnetism

  2 years ago (Sat, Nov 05, 2022 at 02:22 PM)

 University Of Leeds
According to a new scientific assessment, a peculiar property of the Earth’s magnetic field could help us to work out how our planet was created 4.5 billion years ago.

How did the Earth and Moon form? There are several major theories, most involving a giant impact. They range from a scenario where the impacting object strikes the newly formed Earth with a glancing blow and then escapes, through to one where the collision is so energetic that both the impactor and the Earth are vaporized.

Now researchers at the University of Leeds and the University of Chicago have analyzed the dynamics...   Continue reading ››

Webb telescope makes first unequivocal detection of carbon dioxide in an exoplanet atmosphere

  2 years ago (Mon, Aug 29, 2022 at 03:10 PM)

 University of California - Santa Cruz
For the first time, astronomers have found unambiguous evidence of carbon dioxide in the atmosphere of an exoplanet (a planet outside our solar system).

The discovery, accepted for publication in Nature and posted online August 25, demonstrates the power of the James Webb Space Telescope (JWST) to deliver unprecedented observations of exoplanet atmospheres.

Natalie Batalha, professor of astronomy and astrophysics at UC Santa Cruz, leads the team of astronomers that made the detection, using JWST to observe a Saturn-mass planet called WASP-39b which orbits very close to a sun-like star ab...   Continue reading ››








Here's what a black hole sounds like, according to NASA. Yes, it's 'frightening'

  2 years ago (Mon, Aug 29, 2022 at 11:23 AM)

NASA this week shared an audio clip on social media that allows you to "hear" a black hole.

No surprise, the sound is terrifying.

NASA Exoplanets, a team at the agency focused on planets and other information outside of our solar system, tweeted the 34-second clip on Sunday and said there's a "misconception" that there is no sound in space.

But they explained that "A galaxy cluster has so much gas that we've picked up actual sound. Here it's amplified, and mixed with other data, to hear a black hole."

Key takeaways:

• Roving the Red Planet. NASA’s Perseverance landed on Mars in February 2021 and has been gathering data on the planet’s geology and climate and searching for signs of ancient life.

• What lies beneath. The rover’s subsurface radar experiment, co-led by UCLA’s David Paige, has returned images showing unexpected variations in rock layers beneath the Jezero crater.

• Probing the past. The variations could indicate past lava flows or possibly a river delta even older than the one currently being explored on the crater floor.

The accepted view of Mars is red rocks and craters as far as the eye can see. That’s much what scientists expected when they landed the rover Perseverance in the Jezero Crater, a spot chosen partly for the crater’s history as a lake and as part of a rich river system, back when Mars had liquid water, air and a magnetic field.

What the rover found once on the ground was startling: Rather than the expected sedimentary rocks – washed in by rivers and accumulated on the lake bottom – many of the rocks are volcanic in nature. Specifically, they are composed of large grains of olivine, t...   Continue reading ››

Want to grow plants on Mars? High school student project finds 2 tricks for Red Planet

  2 years ago (Thu, Aug 18, 2022 at 04:09 PM)

The soil and water of Mars are normally too harsh for crops, but research led by a then-high school sophomore finds that alfalfa plants and photosynthetic bacteria might help make Martian soil and water fit enough to support farming.

Feeding crews on Mars will be a major challenge for any long-term human mission there, given the high costs of launching anything from Earth to the Red Planet. Scientists have long sought ways to raise crops on Mars, but its soil is poor in the organic nutrients most plants need to grow, and its water is extremely salty.

Hubble Sees Red Supergiant Star Betelgeuse Slowly Recovering After Blowing Its Top

  2 years ago (Sun, Aug 14, 2022 at 04:40 AM)

 NASA/Goddard Space Flight Center
Analyzing data from NASA's Hubble Space Telescope and several other observatories, astronomers have concluded that the bright red supergiant star Betelgeuse quite literally blew its top in 2019, losing a substantial part of its visible surface and producing a gigantic Surface Mass Ejection (SME). This is something never before seen in a normal star's behavior.

Our Sun routinely blows off parts of its tenuous outer atmosphere, the corona, in an event known as a Coronal Mass Ejection (CME). But the Betelgeuse SME blasted off 400 billion times as much mass as a typical CME!

According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study led by the University of Bonn and the University of Saint Andrews (Scotland) challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth’s second closest galaxy cluster – known as the Fornax Cluster – are free of such dark matter halos.
