Terrestrial detonation models illuminate how type Ia supernovae explode
Explosions in the sky and explosions on land are literally worlds apart. A supernova and a land mine explosion don't seem like they would have much in common. But at the fine level, their mechanisms are not so different: ...

A dark energy driven by star formation
Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to temperature. The Landauer equivalent energy of information carried, or represented by matter, effectively ...
Small but mighty: TESSERACT joins the hunt for dark matter
For decades, people have been trying to directly detect dark matter: the missing mass in our universe. Now, there's a new, super-sensitive detector on the case—and even though it's still in the research and development ...

OGLE-GD-WD-0001 is an extremely hot pulsating pre-white dwarf, observations find
Astronomers from Poland and Germany have performed photometric and spectroscopic observations of a blue variable object designated OGLE-GD-WD-0001. As a result, they found that the investigated object is an extremely hot ...
Gemini South observes ultra-hot nova erupting with surprising chemical signature
Nova explosions occur in binary star systems in which a white dwarf—the dense remnant of a dead star—continually siphons stellar material from a nearby companion star. As the outer atmosphere of the companion gathers ...

Neural network deciphers gravitational waves from merging neutron stars in a second
Binary neutron star mergers occur millions of light-years away from Earth. Interpreting the gravitational waves they produce presents a major challenge for traditional data-analysis methods. These signals correspond to minutes ...

Sharper image: Optics instrument reveals pictures of 'baby planets'
With a sun more than 4.5 billion years old, our solar system is considered "middle-aged," and the pictures of what it might have looked like in its infancy are lost to time. Taking advantage of a sophisticated adaptive optics ...

Astronomers detect new polar cataclysmic variable
Using the ROentgen SATellite (ROSAT), astronomers have discovered a new cataclysmic variable system of the polar subtype. The new polar, which received the designation ZTF J0112+5827, has an orbital period of approximately ...
X-ray signal from Helix Nebula points to planet destroyed by white dwarf
After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: The old star might have destroyed a nearby planet.

FAST telescope confirms 'radio-quiet' nature of selected magnetars
A recent study utilizing the Five-hundred-meter Aperture Spherical radio Telescope (FAST) has confirmed the "radio-quiet" characteristics of four magnetars and one magnetar-like pulsar. Conducted by Ph.D. student BAI Juntao ...

'Ghosts of the radio universe': Astronomers have discovered a slew of faint circular objects
Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.

Study investigates multiwavelength variability of blazar PKS 0727-11
By analyzing multiwavelength data from various space telescopes and astronomical surveys, Chinese astronomers have explored the long-term variability of a blazar known as PKS 0727-11. Results of the new study, published in ...
Water might be older than we first thought, forming a key constituent of the first galaxies
Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier ...

Nine open clusters discovered by astronomers
Astronomers have performed a multiwavelength study of nine open cluster candidates. As a result, they found that all of them are genuine open clusters and characterized by their fundamental properties. The finding was reported ...
Hubble captures new view of the Veil Nebula
In this NASA/ESA Hubble Space Telescope image, Hubble once again lifts the veil on a famous—and frequently photographed—supernova remnant: the Veil Nebula. The remnant of a star roughly 20 times as massive as the sun ...
