Residing in the plane of the Milky Way, where it can not be observed by optical telescopes because of obscuring clouds of interstellar dust, Circinus X-1 is the glowing husk of a binary star system that exploded
in a supernova event just 2,500 years ago.

events.
In addition to identifying these
events, the NERSC simulations also helped them prove that strongly lensed Type Ia
supernovae can be very accurate cosmological probes.
«
In fact, the energy and timescale of the gamma - ray emission is a better match to some types of
supernovae, or to some of the supermassive black hole accretion
events that Swift has seen,» Fox said.
It was created by one of the most violent
events that can happen
in the Universe — a
supernova explosion.
«All the elements that exist — that are here on Earth — that are heavier than iron were either made
in supernovas or other cataclysmic
events in astronomy,» says physicist Clarence Virtue of Laurentian University
in Sudbury, Canada.
Rob Beswick, a co-author of the research paper from the University of Manchester's Jodrell Bank Centre for Astrophysics added: «The explosion of a Type Ia
supernova is a rare
event in the nearby Universe.
An alert system to notify astronomers about Gaia discoveries of transient
events like
supernovae (exploding stars) is already
in operation.
No further bursts were seen
in 90 hours of additional observations, which implies that it was a singular
event such as a
supernova or coalescence of relativistic objects.
At a news briefing at NASA headquarters
in Washington, D.C., today, astronomers told stunning tales of
Supernova 2006gy, the largest such
event ever recorded and one so extreme it existed only
in theory up to now.
When stars run out of gas, they explode
in an
event termed a
supernova.
Three potential
events were considered as part of their research, including; large asteroid impact, and exploding stars
in the form of
supernovae or gamma ray bursts.
Dr David Sloan, Co-author and Post-Doctoral Research Associate
in the Department of Physics at Oxford University, said: «A lot of previous work has focused on «doomsday» scenarios on Earth — astrophysical
events like
supernovae that could wipe out the human race.
Using other lensed galaxies within the cluster and combining them with the discovery of the Einstein Cross
event in 2014, astronomers were able to make precise predictions for the reappearance of the
supernova.
Some cosmic rays detected on Earth are produced
in violent
events such as
supernovae, but we still don't know the origins of the highest - energy particles, which are the most energetic particles ever seen
in nature.
In return, the LIGO and Virgo collaborations will be sifting through data to search for gravitational waves that could have been generated by
events, such as
supernova explosions, seen by the conventional observatories.
In the catastrophic
events leading to a
supernova explosion and for roughly 1,000 seconds thereafter, a great variety of nuclear reactions can take place.
The Seagull nebula thus lies at a celestial river fork or street intersection and must be influenced by stellar winds,
supernovae and other
events originating
in both branches of the Orion spur.
Astrophysicists keenly study
supernovae not only to understand the mechanics of stars, but also to learn more about the abundance of elements
in the cosmos, the heavier varieties of which are created by these uncommon
events.
In more massive stars, this cycle of
events can continue, with the stellar core reaching ever - higher temperatures and fusing increasingly heavy nuclei, until the star eventually experiences a
supernova explosion (see below Evolution of high - mass stars).
Some time
in the next several billion years a similar
event will rip apart N55, redistributing cosmic gas and dust as the nebula's constituent stars die
in spectacular
supernovae.
These studies could research
events like
supernovae in incredible detail.
Dr. Stanislav Adamenko, the laboratory's scientific director, believes that these experiments are microscopic analogs of
events occurring
in supernovas and other phenomena involving Z - pinched electrical pulses.36
They had thought about searching for
supernovae, but since
supernovae are such rare
events, they didn't mention it
in their proposal.
A long - standing goal of the LIGO project has been the development of multi-messenger astronomy — the near - simultaneous observation of cataclysmic
events such as neutron star mergers or
supernova explosions
in both gravitational waves and light, providing details about the astrophysics of these phenomena that can't be revealed through either alone.
Stunned astronomers have witnessed a cosmic explosion about 200 times more powerful than a typical
supernova —
events which already rank amongst the mightiest outbursts
in the universe — and more than twice as luminous as the previous record - holding
supernova.
I'm interested
in extreme astrophysical
events like core - collapse
supernovae and compact object mergers.
«There are also two other classes of extreme
events — long duration gamma - ray bursts and superluminous
supernovae — that frequently occur
in dwarf galaxies, as well.
Compare this failure to the studio - engineered failure of Walter Hill's
Supernova: Where
Event Horizon appears strangled
in the womb for its entire second half, Hill's picture, despite the studio - mandated changes imposed on it
in post-production, bristles with ideas about who we are and, more importantly, what our dreams say about us.
Riding on the crest of energy and enthusiasm, 150 bloggers, speakers and partners (sponsored by MSC Cruises and VisitDenmark) attended the
event taking place on a beautiful sunny April weekend taking
in 12 atomic workshops, a galactic Question Time Session, Cosmic Pro Bar one on one sessions, all kicked off by a starry TravelMassive inspired Welcome Party, a
SuperNova AfterParty and finishing off with a supercluster of a Working Breakfast and a PhotoWalk around Brighton that electrified Bohemian Brighton to explode on the seafront causing protests.
GCRs are modulated by both solar magnetic field, which is largely unpredictable
in strength except for generalities associated with 11 - year sunspot cycle and is also modulated by unpredictable
events like nearby
supernovas, and by more predictable very very long slow changes
in intensity due to the solar system traversing spiral arms of our galaxy and wandering above and below the galactic plane
in cycles lasting tens and hundreds of millions of years.
