🆕 This NASA/ESA/CSA James Webb Space Telescope image shows planetary nebula NGC 2392, nicknamed the 'Lion Nebula'. This near- and mid-infrared composite image reveals the complex structure of the nebula 🧪🔭 esawebb.org/images/weic2... @science.esa.int @stsci.edu

$Planetary nebula NGC 2392, also called the Lion Nebula, against the black background of space. The nebula is in the centre, circular in shape, and looks like a male lion’s head. In the very centre is a small, pinkish-white circle with eight-point diffraction spikes, a white dwarf star. Surrounding the star are light purple-pink cavernous bubbles and shell-like rings. The bubbles and shells collectively form an oval with two small, wide arcs near the top, reminiscent of a lion’s face and its ears. What appears to be extended outward from the lion’s face is a thick ring of purple-blue material. The width of the ring is consistent throughout and resembles a mane. The area closest to the lion’s face looks cloudy, while the edges of the mane look like there are clumps of dust with comet-like tails and strands. In the background are distant galaxies and stars. Some galaxies appear as small yellow and orange points of light and others with visible spiral structures. A couple of the stars have diffraction spikes.$

Two python plots. The one on the right shows a continuous function f(x), the Chebyshev nodes it is sampled on and the smooth interpolant. The left plot shows the absolute difference between the original function and the interpolant which is on the order of 10 to the power of negative 9.

Several years on, the results suggest it has delivered broad benefits on safety, public health, travel efficiency, and quality of life.🧵

We mourn the passing of Professor Mike Cruise, who has died at the age of 78. The LISA Consortium extends its sincere condolences to Professor Cruise’s family, friends, and colleagues. Our thoughts are with them at this difficult time.

Professor Cruise played a leading role in the development of the Laser Interferometer Space Antenna (LISA) mission and was instrumental in strengthening the United Kingdom’s contribution to this landmark international endeavour. A distinguished scientist devoted to fundamental research, he made significant contributions to gravitational wave science and to the advancement of space instrumentation. An accomplished educator and advocate of knowledge transfer, Professor Cruise authored the respected
textbook The Principles of Space Instrument Design and mentored generations of students and researchers. Even after formally retiring from the University of Birmingham in 2012, he remained actively
engaged with ESA, the RAS, the UK Space Agency, and the wider gravitational wave community.
