This episode of Space Nuts is brought to you with the support of NordVPN....to get the special Space Nuts deal visit www.nordvpn.com/spacenuts Embark on a celestial detective story in this latest episode of Space Nuts, as your guides through the galaxy, Andrew Dunkley and Professor Fred Watson, unravel the curious case of Venus's quasi-moon. The tale begins with an asteroid that's not quite what it seems, orbiting Venus in a way that defies expectations. The mystery deepens with the asteroid's peculiar name, which comes with its own humorous backstory involving a podcast, a bedroom wall poster, and a case of mistaken identity. Then, shift gears and join the hunt for the universe's elusive sulfur. Why does this common element appear to be hiding in plain sight? The answer lies in the heart of the Milky Way, where a groundbreaking study using the Very Large Telescope has finally solved a long-standing astronomical puzzle. Discover how improved data quality has brought the cosmic abundance of sulfur into clear view, and why planetary nebulae, the final breaths of sun-like stars, are key to this revelation. With Fred on the mend from a pesky tick bite, the dynamic duo delves into the intricacies of celestial mechanics, the naming conventions of space objects, and the importance of sulfur in both the cosmos and our everyday lives. Don't miss this episode of Space Nuts, where the wonders of the universe are made accessible, the seemingly mundane becomes fascinating, and every question leads to a deeper appreciation of the cosmos.

Finnish KitSat-educational satellite has gone missing!

It disappeared near Hyvinkää town in Uusimaa region in Finland, when it landed by parachute from the sky after the flight.

VERITAS Observations of 1ES 1218+304 during the 2019 VHE High State. (arXiv:1908.11836v1 [astro-ph.HE])

1ES 1218+304 is a moderate-redshift (z = 0.182) high-frequency-peaked BL Lac object (HBL). Detected by both the MAGIC and VERITAS gamma-ray observatories, 1ES 1218+304 is frequently monitored by VERITAS as part of its long-term blazar monitoring program. On the 3rd of January 2019, during a regularly scheduled blazar snapshot, VERITAS observed 1ES 1218+304 to have an elevated VHE flux state which continued through January 5 (ATEL #12360). In addition to VERITAS observations, MAGIC also detected elevated VHE emission (ATEL #12354) and Swift-BAT/XRT and Tuorla observations, in X-ray and optical respectively, showed increased multiwavelength activity at the time of the VERITAS observations. In this work, VERITAS observations of 1ES 1218+304 taken as part of a target of opportunity campaign during this elevated state, are presented.

Circle Process

Circle Process in an installation of paper, layering, and shadow studies included in WORK OUT III: Interference Practice, an exhibition of performance and sculpture by artists Monica C. LoCascio, Laura Stoll, and Zsuzsa Rózsavölgyi. 

The work is a preview and post-study from the creation of The Great Wall, a sculpture by LoCascio that will be shown at the Naturhistoriches Museum Wien on June 19th, 2018 in collaboration with Hubble and the European Space Agency. Both works are inspired by the notion of the cosmic web, and humans’ desire to view the large-scale structure of the Universe as a network. 

The original drawings that form the core of both installations are based on astronomical maps of the BOSS Great Wall, a supercluster complex located approximately 5 billion light years from earth. 

The work offers a meditation on questions related to connection and separation: Though the luminous galaxies are separated by vast distances, and yet they are holding onto each other. They are connected. 

Paper, transparency, nylon string, light

Thanks to the BOSS collaboration, especially Maret Einasto (Tartu Observatory) and Heidi Lietzen (Tuorla Observatory) for their help and for providing the scientific data used in this work.

A luminous and isolated gamma-ray flare from the blazar B2 1215+30. (arXiv:1701.01067v1 [astro-ph.HE])

B2 1215+30 is a BL Lac-type blazar that was first detected at TeV energies by the MAGIC atmospheric Cherenkov telescopes, and subsequently confirmed by the VERITAS observatory with data collected between 2009 and 2012. In 2014 February 08, VERITAS detected a large-amplitude flare from B2 1215+30 during routine monitoring observations of the blazar 1ES 1218+304, located in the same field of view. The TeV flux reached 2.4 times the Crab Nebula flux with a variability timescale of < 3.6 h. Multiwavelength observations with Fermi-LAT, Swift, and the Tuorla observatory revealed a correlated high GeV flux state and no significant optical counterpart to the flare, with a spectral energy distribution where the gamma-ray luminosity exceeds the synchrotron luminosity. When interpreted in the framework of a one-zone leptonic model, the observed emission implies a high degree of beaming, with Doppler factor > 10, and an electron population with spectral index < 2.3.
