the Supernova

The most fascinating phenomenon of them all

Space is infinity. An infinity with countless fascinating phenomenon. This site is dedicated to us who adores those phenomena and especially the amazing supernova´s. Even if you´re not denied yet, our mission is to make you feel the fascination that we´ve experienced.

Facts about Supernova

What is a Supernova?

A supernova is an exploding star. The explosion is very violent and can cause the end of a star’s life. In a supernova-explosion is all energy in the star released. This energy would in a normal scenario be emitted during a period of billions of years. This extreme concentrated energy-flow causes an extreme light-explosion that can over-shine an entire galaxy for a moment. It’s this extreme light we can see and identify as a “new” bright star for a restricted time, a supernova.

How can I see a Supernova?

A supernova is just shining for a few seconds and is a pretty rare phenomenon, you shouldn´t count on that you will see one this year. The most recent identified Supernova that was seen from our galaxy, the milky way, was seen in 2005. As a tribute to that supernova we´re named Supernova2005. Even though a Supernova-explosion just is going on for a quick moment it can be seen for a pretty long time from earth, this is because of the very far distance that the light must travel until it´s visible for us.

What is a star?

To really understand what a supernova is all about it´s important to know what a star really are. A star is a big globe made of gas which is mostly made of hydrogen gas. The gravity in the star is enormous and forces the hydrogens to compress and this causes something that is called fusion. The result of the fusion is that all matter in the star, i.e. the hydrogens transforms into energy. The released energy heats the star and makes it shine. The fusion-process in the star is an ongoing process. Thanks to the pressure the fusion causes the star to compensate the gravitation-pressure and for that reason the star stays in its place.

What causes a Supernova-explosion?

When a star grows too heavy to carry its own weight does it start to collapse, and it´s impossible for the star to counteract gravity anymore. When the star starts to collapse all the released inbound energy is released and causes a chain reaction of explosions that turns the star from a star to a huge hydrogen bomb. When this bomb explodes, the supernova is born.

Do all stars become supernovas?

It´s just the biggest stars that can be a supernova. A big star means a heavy star, a star with a compact mass, even double-stars can cause supernova-explosions. The same process as in a supernova-explosion can happen with a smaller star as well, but then, for a explicable reason the explosion is smaller, and then the phenomenon aren’t a supernova, we name those smaller star-explosions Nova´s.

How much energy is it in a supernova-explosion?

During a supernova-explosion can the energy that comes out can be over a hundred times more than the energy that the sun produces in its entire lifecycle. That much energy is quite hard to grasp, it is an enormous amount of energy.

The never-ending story

How can something so destructive be so beautiful? First of all, it´s important to remember that as we said, space is infinity. Space is wide spreading every minute and that means that new stars also are born all the time. That´s always important to remember, supernovas are a never-ending story, how beautiful isn’t that?

What comes after supernova?

When a star has exploded, and turned into a supernova or just a nova the leftovers often cerates what we call a black hole or into a neutron-star.


Here at Supernova 2005 our mission is to create a community and venue where all of us who proudly refer to ourselves as proud supernova-nerds can share our thoughts and knowledge about Supernovas. We want to use our page as a place where we can be able to connecting worlds trough a connected platform, so join our network, be a Supernova-nerd!

Web Seminars

We are currently working on starting up a community connection where it’s going to be possible to interact with other supernova-nerds online. The plan is to arrange web seminars and workshops online for those who want to learn more but don’t have the ability to participate in our live conference. Read more about our workshops and web seminars here

Supernova report

Information about new and old known and famous supernovas. If the rumor about a new visible supernova hits us, we´re publishing it here, so stay tuned.

  • 1006 – An extremely bright and strong supernova was seen from north of the equator according to old scripts.
  • 1572 – A supernova in Cassiopeia was observed by the Swedish scientist Tycho Brahe, his book “The Nova Stella” also gave us the name, supernova
  • 1604 – Johannes Kepler observed a supernova, named Kepelers star. Kepelers star is the only observed supernova in the Milky Way.
  • 1885 – Ernst Hart wig, a German astronomer observed a supernova in the Andromeda galaxy.
  • 1987 – A supernova was observed quite quick after the light had reached all the way to Tell us, this was the first time that modern theories about supernovas was possible to implicate and study.
  • 2005 – A supernova 4,7 billion of lightyears from us was detected, this is the brightest supernova observed in modern time.


Our vision is to arrange a big supernova conference, (not to confuse with the big tech conference that’s held every year in the US named Supernova. That conference has totally another coverage that what this page is about. Even though the name the supernova conference has nothing to do with the fabulous space and infinity, but is still a very pleasant and interesting conference for those of you who´re intressted in technology).

To be able to arrange the conference we´ve already started some preparations. We´ve just booked a local and set a date, those will be released soon, so stay updated and visit the supernova website continuously for updates.

Though, we can tell you all already now that the conference is about to be arranged in Europe, more closely determined, Sweden where we, since there´s no known visible supernovas in the nearest future, will compensate and see another exiting and amazing space-phenomenon, the northern light.

We’ve also already got some partners for the event, who makes it possible for us to arrange the whole conference in Sweden, big thanks to our moving company who is going to help all our visitors, and of course us, to transport all equipment from the airport to our location. We will also send a big thank you to our cleaning company who helps us to clean and prepare the local before we arrive, their work is extra important when it comes to cleaning the big roof windows that the local provides, from which we are going to be able to study the sky also from inside, a really good and important point since Sweden offers a quite cold climate which can make it quite uncomfortable to stay outside for longer periods. We are also planning to visit the Swedish national space board to gain more information about from the experts about our fascinating, amazing space.
