    Discovery of the Oldest Visible Planetary Nebula hosted by a 500-million-year-old Galactic Cluster – a rare beauty with a hot blue heart

    Left panel: An enhanced 6.5 x.5 arcminute colour-composite RGB image of PN IPHASX J055226.2+323724 from the IPHAS survey (Drew et al. 2005) that we confirm as a physical member of the Galactic open cluster M37. Red = Hα, Green = broad band red and Blue = broad band ‘i’. The CSPN is circled in blue; Right panel: 190 x145 arcsecond RGB image created from SDSS with red = i, green = r and blue = g-band. These data clearly shows the faint CSPN (arrowed) at the centre. North is top and East is to the left in both images.

    An international team of astronomers led by members of the Laboratory for Space Research (LSR) and Department of Physics at The University of Hong Kong (HKU), have discovered a rare celestial jewel-a so-called Planetary Nebula (PN) inside a 500 million-year-old Galactic...

    Wataru Kimura and colleagues at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have discovered how the hearts of newborn marsupials retain the ability to regenerate for several weeks. Using this knowledge, the team was able to repair mouse hearts that were damaged a week after birth. The findings, published in the journal Circulation, are expected to contribute to the development of regenerative heart medicines.

    Heart disease is a leading cause of human death and is associated with numerous other secondary illnesses. For humans and other mammals, damaged heart muscle—such as occurs after a heart attack—cannot be naturally repaired because matured heart-muscle cells do not regenerate...

    Researchers demonstrate error correction in a silicon qubit system
    Three-qubit QEC and silicon-based three-qubit device. a. Outline of the three-qubit phase-flip quantum error correcting code. The two-qubit CNOT gates entangle the three qubits, then the Hadamard (H) gates rotate the qubit basis for phase-flip errors. The decoding is the inverse of the encoding. Finally, the correction is performed by a three-qubit Toffoli gate. b. Scanning electron microscope image of the device. Scale bar, 100 nm. The screening gates (brown) are used to restrict the electric field of the plunger (green) and barrier (purple) gates. The three circles (red, green and blue) indicate the position of the triple-quantum-dot array. A further quantum dot shown as the gray circle is used as a charge sensor...

    Here’s what a Black Hole Sounds like, according to NASA. Yes, it’s ‘frightening’

    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.”

    NASA initially released the so-called “sonification” earlier this year, explaining that researchers have “associated” the black hole in the Perseus galaxy cluster with sound since 2003.

    “This is because astronomers discovered that pressure wave...
