  • Bien, sigo experimentando con la porcelana fría que hice. Con la idea de vender objetos relacionados con la astronomía, hice una ballena y un ovalo. Escogí dibujar a Cáncer y Aries respectivamente ya que tienen menos estrellas para formar la constelacion.
.
Luego de pintar las piezas como una galaxia, le agregué un esmalte de uñas con brillitos. En lo personal , me gustaban más sin el esmalte.

  • Astrophysical detection of the helium hydride ion HeH+

During the dawn of chemistry1,2, when the temperature of the young Universe had fallen below some 4,000 kelvin, the ions of the light elements produced in Big Bang nucleosynthesis recombined in reverse order of their ionization potential. With their higher ionization potentials, the helium ions He2+ and He+ were the first to combine with free electrons, forming the first neutral atoms; the recombination of hydrogen followed. In this metal-free and low-density environment, neutral helium atoms formed the Universe’s first molecular bond in the helium hydride ion HeH+ through radiative association with protons. As recombination progressed, the destruction of HeH+created a path to the formation of molecular hydrogen. 
Despite its unquestioned importance in the evolution of the early Universe, the HeH+ ion has so far eluded unequivocal detection in interstellar space. In the laboratory the ion was discovered3 as long ago as 1925, but only in the late 1970s was the possibility that HeH+might exist in local astrophysical plasmas discussed4,5,6,7. In particular, the conditions in planetary nebulae were shown to be suitable for producing potentially detectable column densities of HeH+. Here we report observations, based on advances in terahertz spectroscopy8,9 and a high-altitude observatory10, of the rotational ground-state transition of HeH+ at a wavelength of 149.1 micrometres in the planetary nebula NGC 7027. This confirmation of the existence of HeH+ in nearby interstellar space constrains our understanding of the chemical networks that control the formation of this molecular ion, in particular the rates of radiative association and dissociative recombination.

  • The Crab Nebula and the class of Type IIn-P supernovae caused by sub-energetic electron capture explosions

What sort of supernova gave rise to the Crab Nebula? There are several indications that the Crab arose from a sub-energetic explosion of an 8-10 Msun star, this appears to conflict with the high luminosity indicated by historical observations. This paper shows that several properties of the Crab are best suited to Type IIn-P explosions (Type IIn spectra with plateau light curves). These events probably arise from relatively low-energy (1e50 erg) explosions with low 56Ni yield resulting from electron-capture SNe (ecSNe), but their high luminosity and Type IIn spectra are dominated by shock interaction with CSM. After about 120 days, nearly all of the mass in the CSM and ejecta ends up in a slow dense shell. In the scenario proposed here for SN1054, this thin shell is accelerated by the growing pulsar wind nebula, producing the complex network of filaments seen today. 
There is no need to invoke the invisible fast SN envelope hypothesized to reside outside the Crab. SNeIIn-P explain several observed features of the Crab: (1) No blast wave or rapidly expanding SN envelope outside the filaments, (2) a total mass of 5 Msun swept up in a thin shell, (3) a high peak luminosity despite the low kinetic energy, and (4) chemical abundances consistent with an 8-10 Msun star and low 56Ni yield. A number of other implications are discussed, concerning other Crab-like remnants, dust in the Crab filaments, diversity in the initial masses of SNe IIn, and an association between ecSNe and SN impostors. This model predicts that if light echoes from SN1054 are discovered, they will be consistent with a Type IIn-P spectrum.

  • Hi! This is @akashanandh again and I’m back for the last of my three astro photos in my Universe Today Instagram Takeover today. It has been an absolute pleasure sharing my work with all of you. Hope you liked my astro photos. Let’s work towards a world with less #LightPollution and bring back the magic in the skies. Many thanks to Fraser and @UniverseToday for inviting me again for the takeover and to all you Instagrammers. See you again soon.⁣

45.4% illuminated Waning Crescent, shot about half an hour before sunrise. It was already Astronomical dawn. The moon is one of the few targets to shoot from the light polluted city. As long as the weather permits that is. So I've been shooting the moon as often as I can, and it has been a lot of fun fine-tuning my technique. I enjoy pushing the limits of my modest equipment (my telescope is a 60mm and my camera is a decade-old Canon XSi/450D) by constantly making improvements in my processing methods and any possible changes to my capturing approach. It's a very rewarding experience.⁣

  • ¡Sábado de Mitología!

La constelación de Lepus

Hay diferentes versiones del origen mitológico de la constelación. Algunos dicen que Orión prefería cazar conejos, por lo que el animal fue llevado al cielo con él.
Otra historia habla de la isla de Leros, donde no existían liebres hasta que un visitante trajo un conejo preñado. A los residentes les gustaba el nuevo animal en su tierra, pero se reprodujeron tan rápido que juntos destruyeron casi toda la cosecha.
Como advertencia contra la fertilidad de los conejos, se montó un monumento en el cielo.
